I couldn't find any routines for my problem.the mkl's routines are generally for Hermitian positive definite system. <BR />I would appreciate your help,<BR />Thanks<BR /><BR /><BR /><BR /><BR /><BR /><BR /> Sun, 05 Jun 2011 03:16:20 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/solving-symmetric-but-not-hermitian-matrix-system/m-p/811548#M3966 oguren 2011-06-05T03:16:20Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/solving-symmetric-but-not-hermitian-matrix-system/m-p/811549#M3967 Him<DIV>If your matrix is sparse you could use PARDISO functionality.
