Functions/Subroutines
subroutine, public	cp_fm_struct::cp_fm_struct_create (fmstruct, para_env, context, nrow_global, ncol_global, nrow_block, ncol_block, descriptor, first_p_pos, local_leading_dimension, template_fmstruct, square_blocks, force_block)
	allocates and initializes a full matrix structure
subroutine, public	cp_fm_struct::cp_fm_struct_retain (fmstruct)
	retains a full matrix structure
subroutine, public	cp_fm_struct::cp_fm_struct_release (fmstruct)
	releases a full matrix structure
logical function, public	cp_fm_struct::cp_fm_struct_equivalent (fmstruct1, fmstruct2)
	returns true if the two matrix structures are equivalent, false otherwise.
subroutine, public	cp_fm_struct::cp_fm_struct_get (fmstruct, para_env, context, descriptor, ncol_block, nrow_block, nrow_global, ncol_global, first_p_pos, row_indices, col_indices, nrow_local, ncol_local, nrow_locals, ncol_locals, local_leading_dimension)
	returns the values of various attributes of the matrix structure
subroutine, public	cp_fm_struct::cp_fm_struct_write_info (fmstruct, io_unit)
	Write nicely formatted info about the FM struct to the given I/O unit.
subroutine, public	cp_fm_struct::cp_fm_struct_double (fmstruct, struct, context, col, row)
	creates a struct with twice the number of blocks on each core. If matrix A has to be multiplied with B anc C, a significant speedup of pdgemm can be acchieved by joining the matrices in a new one with this structure (see arnoldi in rt_matrix_exp)
subroutine, public	cp_fm_struct::cp_fm_struct_config (nrow_block, ncol_block, force_block)
	allows to modify the default settings for matrix creation
integer function, public	cp_fm_struct::cp_fm_struct_get_nrow_block ()

integer function, public	cp_fm_struct::cp_fm_struct_get_ncol_block ()
