Function Documentation

poski_vec_t poski_CreateVecView	(	poski_value_t *	vec,
		poski_index_t	length,
		poski_int_t	inc,
		poski_partitionvec_t *	partitionvec
	)

Create a vector-view object.

Parameters:

[in]	vec	Vector data
[in]	length	Logical vector length
[in]	inc	Physical stride between consecutive elements.
[in]	partitionvec	Partitionvector object.

Returns:

A valid vector-view object if success, or an error message otherwise.

This routine performs as follows:

(1) error-check for the input parameters.

(2) allocate space for a new vector-view object, and initialize it.

(3) create partitioned subvectors if partitionvector object is given.

(4) return the vector-view object.

int poski_DestroyVec

(

poski_vec_t

vec

)

Destroy a vector-view object.

Parameters:

[in]

vec

A vector-view object.

Returns:

0 if success, or an error message otherwise.

int poski_check_TwoVectors	(	poski_sparse_matrix_t *	A,
		poski_value_t *	vec1,
		poski_value_t *	vec2,
		poski_index_t	length
	)

Compare two vector data.

This routine compares that two vector data are equal or not.

Parameters:

[in]	A	The sparse matrix object in CSR format.
[in]	vec1	First vector data.
[in]	vec2	Second vector data.
[in]	length	Logical vector length.

Returns:

0 if success, or an error message otherwise.

int poski_report_vector	(	poski_value_t *	vec,
		poski_index_t	length,
		char *	name
	)

Report information of a vector data.

Parameters:

[in]	vec	Vector data
[in]	length	Logical vector length.
[in]	name	Specified vector name.

Returns:

0 if success, or an error message otherwise.

int poski_report_vec

(

poski_vec_t

vec

)

Report information of a vector-view object.

Parameters:

[in]

vec

Vector-view object.

Returns:

0 if success, or an error message otherwise.
