int plasma_cgetri	(	int	n,
		plasma_complex32_t *	pA,
		int	lda,
		int *	ipiv
	)

Computes the inverse of a matrix A using the LU factorization computed by plasma_cgetrf.

Parameters

[in]	n	The order of the matrix A. n >= 0.
[in,out]	pA	On entry, the LU factors computed by plasma_cgetrf. On exit, the inverse of A, overwriting the factors.
[in]	lda	The leading dimension of the array A. lda >= max(1,n).
[in]	ipiv	The pivot indices computed by plasma_cgetrf.

Return values

PLASMA_SUCCESS	successful exit
<	0 if -i, the i-th argument had an illegal value
>	0 if i, the (i,i) element of the factor U or L is zero, and the inverse could not be computed.

int plasma_cgetri_aux	(	int	n,
		plasma_complex32_t *	pA,
		int	lda
	)

Auxiliary routine for plasma_cgetri.

Parameters

[in]	n	The number of columns of the matrix B. n >= 0.
[in,out]	pA	On entry, the upper-triangular part contains the inverse of the U-factor, and the lower-triangular part contains the L-factor, both factors are computed by plasma_cgetrf. On exit, the inverse of L*U, overwriting the factors.
[in]	lda	The leading dimension of the array A. lda >= max(1,k).

Return values

PlasmaSuccess successful exit

void plasma_omp_cgetri_aux	(	plasma_desc_t	A,
		plasma_desc_t	W,
		plasma_sequence_t *	sequence,
		plasma_request_t *	request
	)

Computes triangular solve. Non-blocking tile version of plasma_cgetri_aux(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors. Allows for pipelining of operations at runtime.

Parameters

[in]	A	Descriptor of the matrix.
[in]	W	Workspace of dimension (n, nb).
[in]	sequence	Identifies the sequence of function calls that this call belongs to (for completion checks and exception handling purposes). Check the sequence->status for errors.
[out]	request	Identifies this function call (for exception handling purposes).

Return values

void	Errors are returned by setting sequence->status and request->status to error values. The sequence->status and request->status should never be set to PlasmaSuccess (the initial values) since another async call may be setting a failure value at the same time.

Return values

PLASMA_SUCCESS	successful exit
<	0 if -i, the i-th argument had an illegal value
>	0 if i, the (i,i) element of the factor U or L is zero, and the inverse could not be computed.
