I am looking for a routine in MKL that is equivalent to DGBTRF in LAPACK but only found DGETRF. I think DGBTRF was provided in older MKL, as disucess in this post
Why it is not provided in new MKL releases? If I want to sovle a banded matrix, what is the best way to use subroutines provided in MKL?
MKL provides fully support for LAPACK 3.1. DGBTRF has always been provided, including in the latest MKL 11.1 release. What makes you think it is not available? Did you get a link error? Please give more information.
