09 Feb 2012	mmread Read virtually any media file in Windows, Linux, or Mac. Author: Micah Richert	Works straight out of the box. Simply fantastic, as I've had so many headaches trying to read video data in MATLAB on Linux!
13 Jan 2011	On The Kernel Function Selection Of Nonlocal Filtering For Image Denoising On The Kernel Function Selection Of Nonlocal Filtering For Image Denoising Author: Kanchi	The PDF file that you've included in the submission is copyrighted by the IEEE. You do not have the right to post that here. The MathWorks might be liable for hosting this file...
13 Jan 2011	MATLAB Goto Statement The one and only. Author: Husam Aldahiyat	@Malcom: You can put an "if 0"/"else"/"end" around the two blocks of code. Flipping the 0 to 1 for the first run, then back to 0 to fiddle with the printout. I do that all the time. @Rody: Even with sloppy, quick-n-dirty, messy, one-time-use-only, etc. etc. code, it is much, much, much simpler to use normal flow control than using the GOTO statement. I'm not against the GOTO statement, it wouldn't hurt if MATLAB came with one, but it has very limited uses, mainly in recovering from errors. Actually, considering how well the TRY/CATCH thing works, it might not even be useful there... Having said that, this submission is well written, and shows some interesting uses of MATLAB functionality. I would never have thought that such a function would be possible.
24 Nov 2010	ismatrix1 Work-around for error in built-in function ismatrix (2010b). Only returns 1 for matrices Author: Carey Smith	ismatrix does what the documentation says it does. It seems to not do what you want it to do. I don't see how that's an error. "ismatrix(V) returns logical 1 (true) if size(V) returns [m n] with nonnegative integer values m and n, and logical 0 (false) otherwise."
18 Oct 2010	Summarizes data using a sliding window without loops This function is extremely fast calculating a sum, mean, etc, using no loops. Author: Jeff Burkey	conv(data,ones(N,1),'valid'); does the same as sum(data(repmat(0:N-1,L-N+1,1)+cumsum(ones(L-N+1,N))),2) but is 2 orders of magnitude faster (tested on a 1x1e6 data array). Sure, that doesn't generalize to things other than mean or sum (but note that std and var can be built using the mean filter). Your function is still useful for the median, for example.

28 Jul 2011	cell2str Convert 2-D cell array into evaluable string Author: Cris Luengo	Gaugaz, Julien	Works great for flat cell arrays, but doesn't work for cell-arrays containing other cell-arrays, e.g.: >> utils.cell2str({{1}}) ??? Error using ==> cell2str at 64 Illegal value in cell array.
28 Feb 2011	prettyplot Prettier line plots with markers. Author: Cris Luengo	Aldahiyat, Husam	Great function!
14 Oct 2010	Snakes with class Implementation of snakes using a class to enable automatic display of the snake over an image. Author: Cris Luengo	Luengo, Cris	Vivek, It's explained in the README file inside the ZIP that you download here. You need to install DIPimage (from http://www.diplib.org/). Then copy the two M-files "snakeminimize.m" and "dip_snake.m" to the "dip/common/dipimage/" directory and the M-file "private/paramtype_snake.m" to "dip/common/dipimage/private/". You might need to CLEAR FUNCTIONS before you can use these functions. Please let me know what it is that is not working! Cris.
14 Oct 2010	Snakes with class Implementation of snakes using a class to enable automatic display of the snake over an image. Author: Cris Luengo	Vivek	hi, i'm having Matlab 7.8.0 R2009 in windows platform, could you please let me know, how to run this file?
18 Jun 2010	prettyplot Prettier line plots with markers. Author: Cris Luengo	Kylberg, Gustaf	I was looking for an alternative to the Matlab function plot to solve this specific problem with lines on top of markers, so thank you! Funny that I found your function via Matlab Fileexchange when you have written the function "inhouse" =)

09 Feb 2012	export_fig Exports figures nicely to a number of vector & bitmap formats.	Kevin Moerman	I've tested this for some patch graphics and pdf export. If I just use: export_fig test.pdf, Then for intersecting patch objects (without transparency)it sometimes places the wrong patch objects in front. Other than that very nice.	Comment only

27 Jan 2012	export_fig Exports figures nicely to a number of vector & bitmap formats.	Ken Campbell	Oliver was extremely helpful when I contacted him with a question. His page http://sites.google.com/site/oliverwoodford/software/export_fig also provides many helpful tips.	5
27 Jan 2012	export_fig Exports figures nicely to a number of vector & bitmap formats.	Oliver Woodford	alexancer: Yes. I don't recommend exporting large patch-based objects to EPS. Better to create a resterized version (e.g. export to PNG) then embed in an EPS file using an external application.	Comment only
