Detailed Description

Auxiliary data structure for matrix (potentially memory-mapped, or distributed)

Author: J Benda

Date: 2021 - 2022

Matrix class that either contains allocated data, or pointer to a mapped memory. Used in MolecularData for inner dipole matrices and for boundary amplitude matrices. If the logical flag "distributed" is set to true before reading data, the matrix will be read using MPI-IO into a ScaLAPACK-compatible block-cyclic distributed matrix.
