Factorize Unsymmetric Dense matrix without use of ipiv
Posted: Tue Aug 31, 2010 6:44 amDear Friends
I am new to this forum and this is my first question. I want to factorize a dense matrix using lapack, but without interchanging any rows, i.e, the rel_pivot factor is set to 0. dgetrf interface does not allow this since it will swap the rows internally. Is there any way in lapack I can do this - disallow row interchanges, or set the rel_pivot factor, or specify a static pivot order ?
I can modify the netlib blas routine to suit my application but I would prefer to use any existing lapack routine that already does this.
Thank you
