Detailed Description

A module for an iterator that allows one to easily iterate over elements.

Function/Subroutine Documentation

next()

pure subroutine, public sparsematrixiteratormodule::next	(	type(sparsematrixiterator_t), intent(inout)	this,
		type(sparsematrix_t), intent(in)	sparse_matrix
	)

Gets the next element in a sparse matrix.

Parameters

[in,out]	this	the sparse matrix iterator.
[in]	sparse_matrix	the sparse matrix associated with the iterator.

Todo:

it's probably a pain to have to pass the sparse matrix here. But Fortran's requirement that everything that is pointed to has the TARGET attribute is problematic.

start()

pure subroutine, public sparsematrixiteratormodule::start	(	type(sparsematrixiterator_t), intent(inout)	this,
		type(sparsematrix_t), intent(in)	sparse_matrix
	)

Associates an iterator with a given matrix and points it to first element.

Parameters

[in,out]	this	the iterator to associate.
[in]	sparse_matrix	the matrix to associate it with.
