Function/Subroutine Documentation

dbt_tas_reshape()

recursive subroutine, public dbt_tas_reshape_ops::dbt_tas_reshape	(	type(dbt_tas_type), intent(inout)	matrix_in,
		type(dbt_tas_type), intent(inout)	matrix_out,
		logical, intent(in), optional	summation,
		logical, intent(in), optional	transposed,
		logical, intent(in), optional	move_data
	)

copy data (involves reshape)

Parameters

matrix_in	...
matrix_out	...
summation	whether matrix_out = matrix_out + matrix_in
transposed	...
move_data	memory optimization: move data to matrix_out such that matrix_in is empty on return

dbt_tas_replicate()

subroutine, public dbt_tas_reshape_ops::dbt_tas_replicate	(	type(dbm_type), intent(inout)	matrix_in,
		type(dbt_tas_split_info), intent(in)	info,
		type(dbt_tas_type), intent(out)	matrix_out,
		logical, intent(in), optional	nodata,
		logical, intent(in), optional	move_data
	)

Replicate matrix_in such that each submatrix of matrix_out is an exact copy of matrix_in.

Parameters

matrix_in	...
info	...
matrix_out	...
nodata	Don't copy data but create matrix_out
move_data	memory optimization: move data to matrix_out such that matrix_in is empty on return
