Function Documentation

ghost_error ghost_sparsemat_create	(	ghost_sparsemat **	mat,
		ghost_context *	ctx,
		ghost_sparsemat_traits *	traits,
		int	nTraits
	)

Create a sparse matrix.

Parameters

[out]	mat	Where to store the matrix
[in]	ctx	An existing context or GHOST_CONTEXT_INITIALIZER.
[in]	traits	The matrix traits. They can be specified for the full matrix, the local and the remote part.
[in]	nTraits	The number of traits.

Returns

GHOST_SUCCESS on success or an error indicator.

Note

No memory will be allocated in this function. Before any operation with the densemat is done, an initialization function (see Sparse matrix initialization) has to be called with the sparsemat. As such, ghost_sparsemat_create does not check the matrix datatype stored in traits (GHOST_DT_NONE by default); this is done by the matrix initialization functions to allow for the datatype to be determined from an input file.
