Lower triangular matrix of a symmetric sparse matrix

vahid_s_ — Fri, 06 Dec 2013 23:37:21 GMT

Hi,

Is there any way to get lower (or upper) triangular matrix of a symmetric sparse matrix from pardiso solver? If not, what is the best way to do that using MKL intel in FORTRAN? I know I can get lower triangular matrix of a symmetric matrix with pbtrf() function but I could not find an function for sparse matrices!

The size of symmetric sparse matrix is around 10000*10000.

Thank you,

Vahid

Hi Vahid,

This option is available at www.pardiso-project.org. Please send me an email so that we can discuss if offline.

Hi Vahid,

Nice to see you again! Can I ask you about format of your matrix?

Thanks,

Alex
