Re: Sort a sparse matrix in descending order

Thanks for the comments,us.
I just tried it out and it does work on a 2-dimentional matrix. And
the example you gave seemed not to work properly either. Although it
did sort non-zero elements in descending order, it did not re-arrange
the sorted matrix so that all zeros are at the bottom of the matrix.

More help needed.
