13 Nov 2009	mtit: a pedestrian major title creator MTIT creates a major title in a figure with many axes Author: us	us	this happens by design: after MTIT terminates, the current (active) axis (GCA) is the handle of the invisible surrounding axis created by MTIT... i've changed this behavior and an update should show up soon... in the meantime, you can use this (tedious) approach % create your figure/axes cah=gca; % <- save current axis handle mtit(gcf,'foo'); axes(cah); % <- reset current axis handle us
07 Nov 2009	MATLAB Contest - Flooding All the files needed to develop and score an entry for the MATLAB® Programming Contest. Author: The MATLAB Contest Team	us	just a very marginal note: this version of GETCOMPLEXITY's number-extraction-engine(!) is about 25% faster and does not use EVAL... function mc=getComplexity(filename) mc=mlint('-cyc','-string',filename); mc=regexp(mc,'The McCabe complexity of \S+ is (\d+)','tokens'); mc=[mc{:}]; mc=max(strread(sprintf('%s\n',mc{:}))); end us
24 Oct 2009	finding_ensemble_parameters_of_random_signal_in_a_communication_channel Find ensemble parameters of random signal in a communication channel. Author: Dimuthu Senanayaka	us	in addition to <jan>'s already thorough review: RUN is a ML stock function, which should not be duplicated... us
21 Oct 2009	Quick routine to plot RGB overlay of three images plotRGB allows quick plotting of an overlay of three grayscale images Author: Lennaert	us	...min(min(X)) would be a faster as min(X(:))... not quite % ic2/2*2.6ghz/2gb/winxp.sp3/r2009b x=rand(1000); tic;for i=1:1000;min(x(:));end;toc % Elapsed time is 1.469955 seconds. tic;for i=1:1000;min(min(x));end;toc % Elapsed time is 1.491293 seconds. for smaller xes, its even faster... just a thought us
31 Aug 2009	unique_no_sort_rows find unique rows of a matrix without resorting the rows Author: Michael Petralia	us	does not work on matrices M x N with N > 2, since your statement B = unsorted(:,2:3); should read B = unsorted(:,2:end); us
29 Aug 2009	BlobsDemo Image Processing Tutorial to demonstrate the basic concepts to beginner users. Author: Image Analyst	us	an excellent and exceptionally well commented image processing demo by a seasoned ML user and senior CSSM citizen... a few changes i'd make: - put it into a function -> no need for the bad CLEAR ALL... - make the figure size smaller -and- - put an ECHO ON/OFF at the beginning/end of the demo -> for users to be able to enjoy the comments during run-time... just a few thoughts us
19 Aug 2009	MATLAB rooms KMN Color simulation of the neural instants physicity. Author: PXlab	us	yes, the big number of rows, eg function KMN % MIB & ColorWeight2 ... fprintf('\n'); fprintf('\n'); fprintf('\n'); ... could be simplified into ... fprintf('\n\n\n'); ... with a more recent version of ML (if i'm not mistaken: starting with 2008b) us
19 Aug 2009	ColorWeight (double version) The color weight without weight. Author: PXlab	us	when we run your nice colorweight2 using lena.jpg as an input with parameters to select a row of time in seconds (1-30100): 12 to select a column of space in meters (1-30100): 12 to select the red color (0-300): 12 to insert a positive number of weight [Kg] with range 1-1000: 12 we get this result point of half: clock verse dynamic solution without weight time = 0 % <- ok, same val space = 0 % <- ok, same val velocity = -11 % <- YES, we got the same value(!)... acceleration = -11.917 (!?!) % <- SEE NOTE... mass = 0 % <- ok, same val weight force = -11 % <- ok, same val however, when we use our own algorhythm, we get acceleration = -11.921 which is grossly different and now jeorpadizes our next submission to NEUROLOGY... please, clarify immediately as this is soon going to cause some real problems - if not havoc - for the scientific world... us
19 Aug 2009	MATLAB rooms KMN Color simulation of the neural instants physicity. Author: PXlab	us	the syntax of some of your commands and the flow of your engine in general could be vastly improved if you upgrade your rather old ML version to a new one... us
13 Aug 2009	fdep: a pedestrian function dependencies finder FDEP dissects ML files and iteratively looks for all user defined functions used during runtime Author: us	us	hi dirk great suggestion for an enhancement!... i built a helper function, which does what you need and will email it to you if you want... it will become part of FDEP as soon as i can get to it... us
12 Aug 2009	Mixing / Combining 2 Images (Image Fusion) This program fuses/combines/mixes 2 images It supports both Gray & Color Images Author: Athi	us	how can this earn 5 stars(?)... a script that clears the workspace without asking, no help, no explanation, no comment, no choice of input... us
10 Aug 2009	ds group contribution Author: naser rezakhani	us	a script, no help, no explanation, no comment, no choice of input, idiosyncratic and undecipherable values... us

01 Aug 2009	exciseRows A helper function. Removes all rows with NaNs. Author: Alexander Taylor	us	no need to introduce a different output arg... simply do this function mat=exciseRows(mat) mat(any(isnan(mat),2),:)=[]; end two more things - the help section does not yet live up to standards... - there are no sanity checks... us
28 Jul 2009	35 Complete GUI Examples 35 working GUIs to read and learn. Author: Matt Fig	us	this first class ML senior has offered an enormous amount of time to create this exhaustive suite of working and highly educational GUI examples to our community... both novices, in particular, as well as more advanced users will find a lot of good stuff in those exemplary functions... this submission certainly will find its way into many CSSM threads as a hint for solutions as well as good programming practice... altogether, hats off not only to a ML cognoscente but also to a teacher who clearly seems to be fond of people 'doing' ML... us ps: matt, what about a small CONTENTS.M, which would be easier than the (nice) PDF you proved (just a pedestrian thought)...
27 Jul 2009	fdep: a pedestrian function dependencies finder FDEP dissects ML files and iteratively looks for all user defined functions used during runtime Author: us	us	jason yes, this is by design... while it could easily be changed, it also (potentially) would lead to undesirable results... thus, to FDEP a file residing in a folder, which is not in ML's path, you must CD into that folder... however, let me know if this is a real problem for you, as it certainly can be changed... us
26 Jul 2009	SDF - Set the Figure Set the line width and fonts of a figure, as if using the File->Export setup in the figure menu Author: Andrey Popov	us	well done... now, the next step to get the 5th star: 1) add an output arg, which returns the current STYLE struct... 2) now, a user can change fields to his/her liking - and save it... 3) allow the user to enter his/her (modified) struct... eg, if isstruct(varargin{1}) style=varargin{1}; %... end all done in a split... and a big enhancement to an already nice function... us
22 Jul 2009	SDF - Set the Figure Set the line width and fonts of a figure, as if using the File->Export setup in the figure menu Author: Andrey Popov	us	it would be nice, if a user could also input the name of his/her style sheet: add this to the engine function sdf(fig,snam) if nargin == 1 % your code else % note: REMOVE extension, which is .txt by def s=hgexport('readstyle',snam); % ...apply style sheet info hgexport(fig,fnam,s); end just a thought... us
22 Jul 2009	largestMax The largest component of all vector and/or matrix inputs. Author: Brian Schrameck	us	another way function r=gmax(varargin) try r=max(cellfun(@(x) max(x(:)),varargin)); catch %#ok error('invalid input argument(s)'); end end us
22 Jul 2009	smallestMin The smallest component of all vector and/or matrix inputs. Author: Brian Schrameck	us	another way function r=gmin(varargin) try r=min(cellfun(@(x) min(x(:)),varargin)); catch %#ok error('invalid input argument(s)'); end end us
02 Jul 2009	Clean up context of anonymous function handles - bug #328733 This submission provides a workaround for MATLAB bug #328733. Author: Volkmar Glauche	us	note: since r2009a you can do this f1=@(x) mod(x,2); f2=str2func(func2str(f1)); - the private workspace issue is the same... us
24 Jun 2009	EXPAND Replicate and tile each element of an array. Author: Matt Fig	us	just like jos, i also felt at first that this - admittedly sleek engine - was more or less a KRON clone; but then your timing convinced me that there was clearly more to it... however, i think you should at least mention KRON in a see also: statement... us
22 Jun 2009	RGB triple of color name, version 2 Returns a Matlab RGB color specifier corresponding to a given color name (139 colors supported). Author: Kristjan Jonasson	us	excellent in-depth help including many references... easily expandable look-up table engine... certainly very useful for color-freaks... us
19 Jun 2009	geom3d Library to handle 3D geometric primitives: create, intersect, display, and make basic computations Author: David Legland	us	it is too bad that this (apparently) full-fledged software package does not come with an appropriate and modern help/intro/example module called a published m-file... as of now, it is somewhat tedious for a naive user to have to wade through the help sections of the individual help files (or the densly written contents.m) - and it will (most likely) not give your package as much attention as it probably deserves... us
19 Jun 2009	Matrix to file Writes matrix to a file. Arguments: matrix and file-name Author: Nicolai Sten	us	as was mentioned above, there is (at least) one FEX submission, which does this - with a lot of options... http://www.mathworks.com/matlabcentral/fileexchange/23840 us
08 Jun 2009	fdep: a pedestrian function dependencies finder FDEP dissects ML files and iteratively looks for all user defined functions used during runtime Author: us	us	with the latest version (08-Jun-2009 22:24:13/R14-R2009a), per isakson's error messages do not show anymore... the reason was an old parser engine, which did not handle more recent function constructs... thanks, per, for alerting me to this problem... us
02 Jun 2009	Sudoku This is a Sudoku game that is able to generate new games by itself. Author: Zhen Qian	us	useless without M-code... us
02 Jun 2009	ScreenCapture - get a screen-capture of a figure frame or component ScreenCapture gets a screen-capture of any Matlab GUI handle, or specified screen area rectangle Author: Yair Altman	us	a very nice robot, which the FEX community has been looking for a long time... two thoughts: 1) in interactive mode, the user looses the data if no output arg is selected, which may be a bit frustrating: a) a warning(?) b) a new figure displaying the result by default(?) 2) we've been using this approach, which may be a bit faster (depending on the size of the capture) by converting the planes in one shot using a macro... % input % xoff/yoff/xlen/ylen % assign after loading java stuff... rob=Robot; % macro conv=@(a,b,c) double(bitand(a,255^b))./255^c; % capture screen contents at this pos rec=Rectangle(xoff,yoff,xlen,ylen); cap=rob.createScreenCapture(rec); dat=cap.getData; buf=dat.getDataStorage; buf=typecast(buf(:),'uint32'); buf=reshape(buf,dat.getWidth,dat.getHeight).'; mm=zeros([size(buf),3]); mm(:,:,3)=conv(buf,1,0); % bitand(buf,255^1)./255^0; mm(:,:,2)=conv(buf,2,1); % bitand(buf,255^2)./255^1; mm(:,:,1)=conv(buf,3,2); % bitand(buf,255^3)./255^2; mm=mm./255; % ...for display in a regular figure figure; set(gca,'position',[0,0,1,1]); image(mm); axis image; axis off; 3) in principle, the robot itself can be used on any screen location; it would be nice - however, admittedly cumbersome - to add this feature us
02 Jun 2009	COMBINATOR -combinations AND permutations Returns 1 of 4 different samplings on the set 1:N, taken K at a time. Author: Matt Fig	us	a very nice package/wrapper for a lot of the combinatorial problems almost daily asked for in the NG - or - as the name implies: a TERMINATOR for combiners... in particular: - excellent help/good example - clean engine divided into intelligible subfunctions - many comments and timings us
27 May 2009	Wrap a long syms equations wraps a long syms equation so that it becomes more readable. Author: Mohannad Hakeem	us	there should be a L1 line in the help section... the help section is broken: add a % between the description and the example... the n_columns variable should be an optional input making it more easy to change than having to edit the file... the result should also be collected in an (optional) output argument... us
21 May 2009	cprintf: a pedestrian ND array formatting and display utility cprintf converts an ND array or ND cell array to a 2D character array and - optionally - a table Author: us	us	gordon, 1) you show the input to FPRINTF; how do you call CPRINTF? 2) the error message indicates that some input values are not defined(?) can you clarify? thanks us

19 May 2009	class2str: creates an eval-able string containing Matlab code describing a variable Creates an eval-like string which represents a variable. Useful for saving data/INI configuration Author: Emmanuel Farhi	us	nice and useful utility... given the release for which it was coded (r13) unfortunately, it does not (yet!) too well for more modern data types: - function handles are recognized and it ends with a error msg - graphics handles, eg, gca/line/etc, are caught by their current value - other classes are decoded into a struct, which may not completely reconstruct the object, eg, c=cfit; % <- a fit object ends up as res=struct(c); some of these (understandable) shortcomings should be mentioned in the help section... us
18 May 2009	cell2num.m convert a cell array to a double precision array Author: Phillip M. Feldman	us	why do you submit another author's (unaltered?) code - just because it's a missing part of one of your own contributions... http://www.mathworks.com/matlabcentral/fileexchange/24109 it would be more prudent to ask the author to submit it him/herself and then add it to the above... us
15 May 2009	Don't let that INV go past your eyes; to solve that system, FACTORIZE! A simple-to-use object-oriented method for solving linear systems and least-squares problems. Author: Tim Davis	us	a truly professional and INValuable package written with a twinkle in the (author's) eye and a must look-at for people dealing with linear systems... one pedestrian thought: why not create a stand-alone object given ML's new and powerful OOP-strength... us
14 May 2009	hostname.m Report the name of computer on which Matlab is currently running. Author: Phillip M. Feldman	us	use of java system calls is (likely) a more os independent way to retrieve such information, eg, http://www.mathworks.com/matlabcentral/fileexchange/20321 us

14 May 2009	get_google_map Retrieve a google map from the command line using the Static Google Maps API. Author: Val Schmidt	us	once the user has set the environment - get the KEY - get DEG2UTM it works quite well for most of the prop/val combinations two thoughts no need to FLIPUD(M) in the function... otherwise, users have to flip it back for imagesc(XX,YY,flipud(M)); colormap(Mcolor); axis image; which seems a faster/better way to display the map compared to the proposed SURF(...) the props should be case-insensitive... us
06 May 2009	findsubmat Finds one matrix (a sub-matrix) within another. Author: Matt Fig	us	observing a master carving out an outstanding masterpiece of a master's workmanship... us
05 May 2009	findsubmat Finds one matrix (a sub-matrix) within another. Author: Matt Fig	us	- very nice: help, example, commented and intelligent engine, acknowledgement of input by another user (excellent academic behavior)... - BUT: unfortunately, it does NOT (yet) handle NANs - nor does it give a warning/error message... - a workaround could be to replace NANs with a unique value not found in either data set (we did this in FEX:FPAT:id:6070)... us
