imagesc plot to matrix in matlab

Question

I would like to save in a matrix the plot that imagesc returns. How can I do that? All I know that imagesc returns a handle and I don\'t know what to do with it.

Answer 1

The data for imagesc is stored in the CData property, so use this to extract it:

X = get(h, 'CData');

assuming h is your handle.

Now X contains your image data, and you can save it to a file, for instance:

save somefile.mat X
