Replace LINPACK with LAPACK in DASSL #10

Open ivan-pi opened 7 months ago

ivan-pi commented 7 months ago

The DDASSL routine uses the following double precision LINPACK routines:

DGEFA/DGESL
DGBFA/DGBSL

with dependencies on the following BLAS routines:

DSCAL
DAXPY
DDOT
IDAMAX

Ideally, we should replace the LINPACK routines with their equivalent LAPACK replacements: DGETRF/DGETRS (general) and DGBTRF/DGBTRS (banded).
