Functions/Subroutines
subroutine, public	cp_fm_types::cp_fm_create (matrix, matrix_struct, name, use_sp)
	creates a new full matrix with the given structure

subroutine, public	cp_fm_types::cp_fm_init_random (matrix, ncol, start_col)
	fills a matrix with random numbers

subroutine, public	cp_fm_types::cp_fm_set_all (matrix, alpha, beta)
