04 Nov 2009 flat flatten a matrix, i.e. make it a vector Author: Vincent

After having had this file in my librarby now for a moth, I am upping the rating to a five. The help section is still kinda child-like, but the fact is that there is no file-exchange sumbission I have used more than this little piece of code.

It may be trivial, and self-named gurus might find it beneath them to use it, but for those of us who code matlab for a living and need to type legible code accurately and fast, it is a perfect tool.

In particular:
a = rand(3,4,5,6);
b = mean(flat(a(:,1,:,2));

Is as legible and as hard to get wrong as they come.

28 Aug 2009 Printing Variables to HTML Tables in Published Code This file lets you display variables as HTML tables in your published MATLAB files. Author: Ned Gulley

Awsome potential, but it eems to depend on a function called nanmin which is not included in basic Matlab. Either include an implementation, or post a link to an implementation that is compatible.
24 Aug 2009 Lomb normalized periodogram Both functions calculate the Lomb-Scargle periodogram (aka Gauss-Vanicek/Least-squares spectrum) Author: Christos Saragiotis

Nice implelemtation of the Lomb method. The only reason I am not giving this a five is that the built-in plotting functionality is far to over-specified. Opening up a new figure and then drawing raw lines in it is not particularly flexible or helpful for integrating into larger applications.
11 Aug 2009 freezeColors / unfreezeColors Use multiple colormaps per figure! Version 2, now works for many types of objects, not only images. Author: John Iversen

Neat program, but I found a bug:
Running the following line:
>>image; freezeColors

gives the following error message:
??? Subscript indices must either be real positive integers or logicals.

Error in ==> freezeColors at 136
        c = cmap(idx,i);

Placing a breakpoint and looking at idx on the line in question reveals that idx consists of floating point numbers and not integers at that point.

Unfortunately, I do not have enough of an understanding of the program to present a fix.
11 Aug 2009 Fast imrotate A fast version of imrotate Author: Ilan Ben Hagai

You might want to considder making your demo self-contained, that is you include the circuit.tif into the zip file.

16 Oct 2009 Call A mex file for calling external applications from within matlab. Author: Daniel Armyr Simon, Jan

The author states, that the function is less useful than Matlab's SYSTEM command. He rates his function with 1 star, but does not remove it from the FEX. After all it is downloaded 101 times this month! I'm really curious about your reasons for downloading - can you write some comments, please?
21 Jul 2009 Advanced Polar Plots v2 An improved version of the MATLAB function 'polar'. Author: Daniel Armyr Mohamad

I'm plotting normalized power radiation pattern in dB scale 0 to [-inf]. Your code does not seem to work at all when 0 is defined as the maximum value. When I try with other data with 0 as the least value, your code works awesome.

02 May 2009 Advanced Polar Plots v2 An improved version of the MATLAB function 'polar'. Author: Daniel Armyr Armyr, Daniel

To be clear, I have given upp support of this function in favour of "polar 2" which can be found here.
http://www.mathworks.com/matlabcentral/fileexchange/23589

Polar 2 has less features, but has relatively cleaner code and is less prone to bugs.

If someone else wants to maintain this file, feel free. Just do the bugfixes and upload it under your own name,
01 May 2009 Advanced Polar Plots v2 An improved version of the MATLAB function 'polar'. Author: Daniel Armyr Brian

There is a typographical error in line 180.

'oc_ring_border_line_width'
should be
'oc.ring_border_line_width'

Cheers.
20 Apr 2009 Advanced Polar Plots v2 An improved version of the MATLAB function 'polar'. Author: Daniel Armyr Jonas

There is an error at least on OS X - the variables TraceMax and TraceMin are initialized as empty stings, which leads to strange behavior when catenating with doubles.
This leads to the error 'Centre value is same as maximum input value' being thrown erroneously.

I suggest changing lines 1326 and 1313 to
TraceMax = [];
TraceMin = [];
respectively.
