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

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!

You may use LS with wildcard '*' and that's it.

06 Oct 2009 tlabel.m v2.6.1 (Sep 2009) Same as DATETICK but with ZOOM, PAN, LINKAXES and more! Author: Carlos Adrian Vargas Aguilera Vargas Aguilera, Carlos Adrian

Hi Stefan, as far as I know, that functionality of the ZOOM and PAN functions does not work even on the first version of MATLAB v7.

One workaround is to edit "temporarly" the ZOOM/PAN function by adding the line
datetick('keeplimits')
at the end.

Or make your one function

function myzoom()
zoom
datetick('keeplimits')

and run
>> datetick
>> myzoom

Let me know if it works for you. Via email if possible.

31 Jul 2009 plots.m, plotses.m Plots each column of a matriz vs a single axis. Improvement of plotyyy. Author: Carlos Adrian Vargas Aguilera Vargas Aguilera, Carlos Adrian

To use 'reverse' in 'YDir' (or in 'XDIr' if 'left' o 'right' was used) in the included example use:

bt = 2; % 1=='bottom', 2=='top'
ylim = get(he,'YLim');
N = length(he);
for k = 1:N
 d = ylim{1}(1,bt)-ylim{k}(1,bt);
 ylim{k} = [ylim{1}(1,1)+d*(bt==2) ylim{1}(1,2)+d*(bt==1)];
end
set(he,{'YDir','YLim'},[repmat({'reverse'},N,1) ylim])

Cheers, the author
01 Jul 2009 sturm Second order ODE solver using linear finite elements. Author: Alexander Pletzer Vargas Aguilera, Carlos Adrian

Incredible simple program It solves the inhomogeneous sturm-liuville system and the homogeneous one (with EPS forcing) although not the eigenvalues.

Great job Alexander, please update it.

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

Yes (kind of) but first, why would you like to do so if you can do it with PCOLOR? Well...

% Change line 359:
if aequal
%by:
if 0

% On empty line 398 write:
U = [U U(:,end); U(end,:) U(end,end)];
% Which is the trick. You may try other ways.

% Finally, change line 404:
'FaceColor','flat',...
% by:
'FaceColor','interp',...

% And that is it. Try imagescnan(peaks(5)) and you'll see the problem, which is that the interpolation is done on the edges and not on the middle of the faces (sort of). Maybe some day...

Saludos, Carlos Vargas
09 Jun 2009 imagescnan.m v2.1 (Aug 2009) Same as IMAGESC but ignores NaNs. Author: Carlos Adrian Vargas Aguilera Vargas Aguilera, Carlos Adrian

I guess not Yu-nung, the program may flip the image if your axes are decreasing, but never the ticks. Try a normal IMAGESC or send me your script. Carlos
22 Apr 2009 readline.m v3.0 (Jun, 2009) Reads the specified line(s) from a file. Author: Carlos Adrian Vargas Aguilera Vargas Aguilera, Carlos Adrian

Is not true Gabriel, it need to be like that so to be able to generate range from negative inputs. The author.
20 Mar 2009 smooth2a Smooths a 2D matrix using a mean filter over a user-defined rectangle. Ignores and preserves NaNs. Author: Greg Reeves Vargas Aguilera, Carlos Adrian

Nice code, my codes moving_average.m and ndnanfilter.m do similar jobs but are written very different! Regards...
11 Nov 2008 Wind_rose Wind rose of direction and intensity Author: M MA Vargas Aguilera, Carlos Adrian

Dear D S: you should write this kind of quenstions on the Newsreader (where many people will be glad to help you) or write directly to the author. Look at 5 statements here below. Carlos
24 Oct 2008 plots.m, plotses.m Plots each column of a matriz vs a single axis. Improvement of plotyyy. Author: Carlos Adrian Vargas Aguilera Vargas Aguilera, Carlos Adrian

You just need to use >> set(he(1),'Xlim',[0 1]), to modify the limits of the first axes from 0 to 1. Carlos
