This example reads a full matrix representing a scattering matrix from disk, and compress it using entry-evaluation or matvec-based APIs.
Note that instead of the use of precision dependent subroutine/module/type names "z_", one can also use the following
#define DAT 0
#include "zButterflyPACK_config.fi"
which will macro replace precision-independent subroutine/module/type names "X" with "z_X" defined in SRC_DOUBLECOMLEX with double-complex precision
