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!

Great functions. Only my comments after a three points were left!

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

Hi Carlos. I like your function, but it is not working 'correctly' when using a plot with more than two y-axes, like produced with the function 'ploty4' (can be downloaded on file exchange). Here the plots in different axes are drawn away from each other. Suppose that two lines y1(x) and y2(x) are crossing at a special point (x0,y1(x0)=y2(x0)). If I zoom on the plot in the axes of y1 at the point, (x0,y1(x0)) The lines will not cross anymore. 'linkzoom' moves the axes differently.

Hi Carlos,

This is potentially awesome!

However, I've got two concerns:

1. There may be a bug for some inputs. I tried to get derivative (in the columnar direction) of a lot of vectors in a 3D array, and get:
F = rand(10,10,10);
h = [1 1 1];
Wn = 9;
Deg = 2;
Pad = 'replicate';
[dF1,dF1std] = der(F,h,Wn*h(1),Deg,Pad,1);

??? Error using ==> reshape
To RESHAPE the number of elements must not change.
Error in ==> polyGradient>der at 245
  T = reshape(permute(DT,[DIM 1:DIM-1 DIM+1:Ndim]),m,n);

2. The mlint code analyser highlights a possibly ill-conditioned use of inv( ) at line 365. Is it justified, or is in not possible to use \ for this computation?

Thanks so far, it's looking like this will be very useful, even if only limited to 1D.

Kind regards

Tom
