PLASMA - Parallel Linear Algebra for Scalable Multi-core Architectures
int PLASMA_sgetri_Tile ( PLASMA_desc A,
int *  IPIV 
)

PLASMA_sgetri_Tile - Computes the inverse of a matrix using the LU factorization computed by PLASMA_sgetrf. This method inverts U and then computes inv(A) by solving the system inv(A)*L = inv(U) for inv(A). Tile equivalent of PLASMA_sgetri(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors.

Parameters
[in,out]AOn entry, the triangular factor L or U from the factorization A = P*L*U as computed by PLASMA_sgetrf. On exit, if return value = 0, the inverse of the original matrix A.
[in]IPIVThe pivot indices that define the permutations as returned by PLASMA_sgetrf.
Returns
Return values
PLASMA_SUCCESSsuccessful exit
>0if i, the (i,i) element of the factor U is exactly zero; The matrix is singular and its inverse could not be computed.
