Your posted matrix result is not rectangular. You can't have this in a numeric matrix. Is this really what you want for an output or is this a typo? I.e., do you really want the resulting columns to potentially have different numbers of elements? (In which case maybe a cell array would be what you want).

i0 = ~isnan(A);
ii = sort(i0,'descend');
out = nan(size(A));
out(ii)=A(i0);
