05 Jun 2014 COLORMAP and COLORBAR utilities (Jul 2014) MATLAB color utilities including COLORMAP join and interpolation; freeze and fit COLORBAR, etc. Author: Carlos Adrian Vargas Aguilera

Thank you all for your comments. Now the scientific notation 'x10' issues are fixed (well I guess so), and a new way to write it included: using International System Units' prefixes (mega, kilo, etc.).

Cheers, Carlos A.

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!

20 Oct 2014 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 yu, sixie

16 Oct 2014 extrema.m, extrema2.m Search all extrema points of a time series or a surface with/without NaN's. Author: Carlos Adrian Vargas Aguilera Phillip

Using this across a broad range of applications, very handy.

08 Oct 2014 imagescnan.m v2.1 (Aug 2009) Same as IMAGESC but ignores NaNs. Author: Carlos Adrian Vargas Aguilera Kerns, Brandon

Extremely useful for making color shaded plots for publication. PCOLOR gets rendered as patches in a pdf file, which is not optimal because you see the edges of the patches. Using imagesc or isagescnan outputs the shading as an embedded image. There is one bug in which I had the X and Y coordinates as a regular grid with 0.1 intervals, and it thought the grid was irregular and reverted to patches. Fixed by changing 1000 to 10000 on lines 231 and 284. This seemed to work with 0.01 intervals too.
