MATLAB: Delete NaN rows and columns but

delete nan rows and columns butimage analysisimage processing

I want to remove the NaN column and row in my image so the size will be decreased, but since I used the "find' command it Matlab, it also remove the NaN that changes the shape of the image,too. I just want to remove the NaN data as much as possible but keep the other NaNs that cannot be removed in order to have the same shape.

    M( all( isnan( M ), 2 ), : ) = []; % removes all rows with all nans
    M( :, all( isnan( M ), 1 ) ) = []; % and columns
