MATLAB: Display NaNs values and apply alphadata for values different to NaNs

Question

Hello,

I want to display the NaN values by setting an alphadata equal to 0 and at the same time apply an alphadata equal to 0.3 for values different to NaNs?

This is the code i use but it doesn't work:

    im=imagesc(I) 
    set(im,'AlphaData',0.3); 
    set(im,'AlphaData',~isnan(I))

Thanks,

Try this

im = imagesc(I);
im.AlphaData = 0.3*ones(size(I));
im.AlphaData(isnan(I)) = 0;
