UMFPACK ordering options problem with no re-ordering

Hi all

While using umfpack I want to use the natural ordering of my matrix without any fill reducing reorderings, when I used the control in umfpack with control.ordering='none' it is giving an error as "invalid ordering" but the code works fine with amd ordering. Can anyone give a suggestion on this.

Thanks

Hi,

Did you install the package from MATLAB Central File exchange? If so, contacting the author might be helpful.

Thanks.
