csr_create Interface

private interface csr_create

Module Procedures

public subroutine csr_create_new(csr_mat, nrows_total, ncols_total, nze_total, nze_local, nrows_local, mp_group, data_type)

Create a new CSR matrix and allocate all internal data (excluding dbcsr_mapping)

Arguments

Type	Intent	Optional	Attributes		Name
type(csr_type),	intent(out)			::	csr_mat	CSR matrix to return
integer,	intent(in)			::	nrows_total	total number of rows total number of columns
integer,	intent(in)			::	ncols_total	total number of rows total number of columns
integer(kind=int_8)				::	nze_total	total number of non-zero elements
integer,	intent(in)			::	nze_local	local number of non-zero elements local number of rows
integer,	intent(in)			::	nrows_local	local number of non-zero elements local number of rows
type(mp_comm_type),	intent(in)			::	mp_group
integer,	intent(in),	optional		::	data_type	data type of the CSR matrix (default real double prec.)

public subroutine csr_create_template(matrix_b, matrix_a)

Create a new CSR matrix and allocate all internal data using an existing CSR matrix. Copies the indices but no actual matrix data.

Arguments

Type	Intent	Optional	Attributes		Name
type(csr_type),	intent(out)			::	matrix_b	Target CSR matrix
type(csr_type),	intent(in)			::	matrix_a	Source CSR matrix
