10 Aug 2010	COMBINATOR -combinations AND permutations Returns 1 of 4 different samplings on the set 1:N, taken K at a time. Author: Matt Fig	Oops, that was an error of omission on my part. I will post an update. Thanks Jan.
16 Jun 2010	cell2char Function to convert a cell array of strings into a character array. Author: Tonatiuh Pena Centeno	I see, your code handles cells like this: C = {'poss';'pess';'asdf';NaN;44;pi;'cookie'} So it is the description you give that needs fixing. It does more than convert the contents of a cell array of strings. It converts the contents of a cell array of strings and/or numbers. However, couldn't your entire algorithm be replaced with this? S = char(cellfun(@(x) num2str(x),C,'Un',0))
16 Jun 2010	cell2char Function to convert a cell array of strings into a character array. Author: Tonatiuh Pena Centeno	Maybe I missed it, but what does CELL2CHAR(C) do that CHAR(C) does not do? And CHAR is a built-in!
10 Jun 2010	CHECKVARS Checks for function masking by variables in an M-File. Author: Matt Fig	It was brought to my attention that there are a few short-comings in the file. The file will be updated shortly.
21 May 2010	Anti-diagonal matrix traversal This function allows you to traverse a square matrix along the anti-diagonal. Author: Loïc	As it is, you have some deficiencies. There is no H1 line. The help is non-standard in its location. There is no input checking: if the function is for square matrices then you should check to see if the input is square. Your algorithm works well, except you cripple the speed by not pre-allocating your return arrays before the loops. Look at the difference: >> M = round(rand(400)*300); >> tic,[P,Q]=diagtrav(M);toc % No pre-allocation Elapsed time is 134.937511 seconds. >> tic,[P,Q]=diagtrav(M);toc % With pre-allocation Elapsed time is 0.014006 seconds. You should pre-allocate the return arrays!

18 Aug 2010	41 Complete GUI Examples 41 working GUIs to read and learn. Author: Matt Fig	Couzi, Camille	HI!!!! One question about GUI_27: How can I get the same results, knowing that my figure of GUI, and all buttons and panels are deinfed in units normalized? Thanks you very much!!!

09 Aug 2010	COMBINATOR -combinations AND permutations Returns 1 of 4 different samplings on the set 1:N, taken K at a time. Author: Matt Fig	Simon, Jan	Your first submission contained the source code cumsumall.cpp. Now I find only the compiled mexw32. It would be nice to have the source again, to allow all non-Windows and the 64 bitters to work with COMBINATOR.
13 Jul 2010	41 Complete GUI Examples 41 working GUIs to read and learn. Author: Matt Fig	Lacerda, Luis	hello, i have read the examples but i still can´t answer my question...how can you make a GUI subplot something in another GUI? Not just plot, because what i am plotting has parameters altered by the called GUI.. thanks

10 Mar 2010	Bipolar Colormap Symmetric/diverging/bipolar cold-neutral-hot colormap	Jody Klymak	I'd also take a look at: http://www.mathworks.com/matlabcentral/fileexchange/17555-light-bartlein-color-maps	Comment only
08 Dec 2009	Bipolar Colormap Symmetric/diverging/bipolar cold-neutral-hot colormap	Ged Ridgway	Dear Oliver, thank you very much for your feedback. Regarding the flipping, bipolar takes an optional second argument which specifies the gray-level value of the neutral color, and the ends are actually automatically flipped around if you specify a whiter shade of pale gray. E.g. if you specify 1, you get blue-cyan-white-yellow-red. Personally, I don't think this looks as nice, but that is of course subjective. Regarding your other colormaps, I'm afraid I personally find the same perceptual issue with "bright" (purple bands above and below the pure blue) and with "pastel" (to a small extent but in several places). I really like your thermal and temp colormaps, however, I am particularly keen on having a neutral mid-gray in the centre of the map (which was the reason I focused on hicontrast), rather than white (as in temp) or red (as in thermal). I will play around with modifying CMRmap, thermal and temp, to see if I can find something I am really happy with... If you have any further suggestions, they would be much appreciated, thanks!

08 Dec 2009	Bipolar Colormap Symmetric/diverging/bipolar cold-neutral-hot colormap	Oliver Woodford	Ged, real2rgb (id 23342) only linearizes a colormap's absolute gradient in luminance per color entry - they need to be monotonic to start with if you want monotonic output. It has several other monotonic colormaps (which can be linearized) other than hicontrast. Perhaps you'll find one you like. My thoughts on this colormap are that it could look better with the two ends flipped so that they converge on white instead of dark gray. Have you tried it?	Comment only

07 Dec 2009	Bipolar Colormap Symmetric/diverging/bipolar cold-neutral-hot colormap	Ged Ridgway	Dear Sjoerd, thank you very much for drawing my attention to Carey Rappaport's CMRmap. It turns out that my colormap is not currently suitable for conversion to grayscale. To some extent, it's actually rather difficult to get good visualisation of bipolar/signed data in grayscale anyway, but it would be nice to have a map that degraded more gracefully. I tried to find a bit more about the theory, but have so far failed. E.g. this site is otherwise very helpful, http://www.personal.psu.edu/cab38/ColorBrewer/ColorBrewer_learnMore.html but says "Differences in lightness should be preserved with sequential schemes" while "diverging schemes cannot be photocopied successfully." In other words, Dr Brewer doesn't attempt to make bipolar schemes with nice grayscale equivalents. I found ID 23342 from a comment on CMRmap, and have just tried it out. Unfortunately, its conversion of my colormap to a linear-gray version doesn't seem to work well; the result is non-monotonic in gray-level (at least when converted from a saved PNG using the Gimp) and additionally translates the neutral gray away from the origin. ID 23342 also has a colormap called hicontrast, with linear grayscale, but I don't really like this, as it seems perceptually non-monotonic in color to me, e.g. either side of cyan you can see a pair of pale green colors, which are (by construction) separated in gray-level, but not really in hue, similarly either side of red is a pair of similar magenta hues. I will try to look into this in more detail and provide an alternative map (necessarily without the user-definable neautral gray-level, as this will have to be at or very near to 0.5) that degrades better to grayscale in a future update... Thanks again for the heads-up!	Comment only
