delete NaN rows and columns but

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.

Is this close?

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

and you might want to try the FEX contribution inpaint_nans

Was just looking exactly for that! Thank you! And thanks showing both (column and rows)! It looks easy to change from row to column if you know how ... but if you don't ... can drive you crazy!
