Thanks a lot Robert,

It works perfect. The algorithm does exactly what I need.

I formulated this not correctly. I have some matrix which is not generated in maple. It is a sparse matrix, which have elements below and above diagonal. An example of such matrix you can see in the txt-file below. But the structure of the matrix can be slightly different. I want to permute the columns in such way that the number of non-zero elements under the diagonal would be minimal.

The question is there any function in maple which can do this? Or should I write an algorithm my self?
