17 Nov 2009 imagescnan.m v2.1 (Aug 2009) Same as IMAGESC but ignores NaNs. Author: Carlos Adrian Vargas Aguilera

Yes Olivier, or with:
>> imagesc(U,'AlphaData',~isnan(U),'AlphaDataMapping','none')
I just wanted to be able to paint NaNs with specifyc color without modifying the axes color.
Probably I should include this "transparent" option. Thank you!

Oh, besides of the NOT ignored lines after "...", also grouped comments are NOT ignored:

04 May 2012 moving_average v3.1 (Mar 2008) Smooths a matrix (with/without NaN's) via recursive moving average method and eliminates data gaps. Author: Carlos Adrian Vargas Aguilera Kottayil , AJIl

I would like to get a moving average function dealing with nan values

30 Apr 2012 extrema.m, extrema2.m Search all extrema points of a time series or a surface with/without NaN's. Author: Carlos Adrian Vargas Aguilera Couzi, Camille

Hola Carlos!
Thanks for your contribution.
I am having some issues though... I am using your function inside a script which uses fminsearch also... and getting the following error message:

Maximum recursion limit of 500 reached. Use set(0,'RecursionLimit',N)
to change the limit. Be aware that exceeding your available stack space can
crash MATLAB and/or your computer.

Error in extrema

Error while evaluating uicontrol Callback

Help! How do I solve this problem!
 Gracias y muchos saludos!
27 Mar 2012 plots.m, plotses.m Plots each column of a matriz vs a single axis. Improvement of plotyyy. Author: Carlos Adrian Vargas Aguilera K, P

Thanks for the code, but I am getting the same error as Matt got:
Error in ==> plots at 62
set(gca,'Position',pos_fix); % New position

Error in ==> F_comparison at 94
[hlines,haxes]=plots(x,Y,location,labels);
22 Mar 2012 extrema.m, extrema2.m Search all extrema points of a time series or a surface with/without NaN's. Author: Carlos Adrian Vargas Aguilera raj

{surf(T,f,G'), shading interp
      [Gmax,imax,Gmin,imin] = extrema2(G);
      hold on
       plot3(T(imax),f(imax),Gmax,'bo')
       for i = 1:length(Gmax)
        text(x(imax(i)),y(imax(i)),zmax(i),[' ' num2str(zmax(i))])
       end
       hold off}
My problem is the T,f,G are of different sizes and an error comes up saying '??? Index exceeds matrix dimensions.' any suggestions please help
