#* Determine superspace group symmetry operators from symmetry matrices.
#* Superspace group symmetry operators are output as parsable strings
#* as described in the CIF _space_group_symop_ssg_operation_algebraic
#* data item.
#*
#* USAGE:
#* $0 < input.matrix
#* $0 input.matrix
#* $0 input1.matrix input*.matrix
