create_col_vec_from_matrix()

subroutine, public dbcsr_vector::create_col_vec_from_matrix	(	type(dbcsr_type)	dbcsr_vec,
		type(dbcsr_type)	matrix,
		integer	ncol
	)

creates a dbcsr col vector like object which lives on proc_col 0 and has the same row dist as the template matrix the returned matrix is fully allocated and all blocks are set to 0 this is not a sparse object (and must never be)

Parameters

dbcsr_vec	the vector object to create must be allocated but not initialized
matrix	a dbcsr matrix used as template
ncol	number of vectors in the dbcsr_typeect (1 for vector, n for skinny matrix)

create_row_vec_from_matrix()

subroutine, public dbcsr_vector::create_row_vec_from_matrix	(	type(dbcsr_type)	dbcsr_vec,
		type(dbcsr_type)	matrix,
		integer	nrow
	)

creates a dbcsr row vector like object which lives on proc_row 0 and has the same row dist as the template matrix the returned matrix is fully allocated and all blocks are set to 0 this is not a sparse object (and must never be)

Parameters

dbcsr_vec	...
matrix	a dbcsr matrix used as template
nrow	number of vectors in the dbcsr_typeect (1 for vector, n for skinny matrix)

create_replicated_col_vec_from_matrix()

subroutine, public dbcsr_vector::create_replicated_col_vec_from_matrix	(	type(dbcsr_type)	dbcsr_vec,
		type(dbcsr_type)	matrix,
		integer	ncol
	)

creates a col vector like object whose blocks can be replicated along the processor row and has the same row dist as the template matrix the returned matrix is fully allocated and all blocks are set to 0 this is not a sparse object (and must never be)

Parameters

dbcsr_vec	the vector object to create must be allocated but not initialized
