Detailed Description

Matrix types and operations for spclibs C++ port.

This file is a C++ translation of the Fortran module matrix.f90 from spclibs. It provides band matrix types compatible with LAPACK routines.

Key types:

GBMat: General band matrix (LAPACK DGBTRF/DGBTRS storage)
GEMat: General dense matrix (LAPACK DGETRF/DGETRS storage)
PBMat: Packed band matrix (symmetric, LAPACK DPBTRF/DPBTRS storage)
PeriodicMat: Periodic band matrix using Woodbury formula
