Modules
module	arnoldi_vector
	operations for skinny matrices/vectors expressed in dbcsr form

Functions/Subroutines
subroutine, public	arnoldi_vector::create_col_vec_from_matrix (dbcsr_vec, matrix, 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)
subroutine, public	arnoldi_vector::create_row_vec_from_matrix (dbcsr_vec, matrix, 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)
subroutine, public	arnoldi_vector::create_replicated_col_vec_from_matrix (dbcsr_vec, matrix, 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)
subroutine, public	arnoldi_vector::create_replicated_row_vec_from_matrix (dbcsr_vec, matrix, nrow)
	creates a row vector like object whose blocks can be replicated along the processor col and has the same col 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)
subroutine, public	arnoldi_vector::dbcsr_matrix_colvec_multiply (matrix, vec_in, vec_out, alpha, beta, work_row, work_col)
	the real driver routine for the multiply, not all symmetries implemented yet
