PLASMA_spotri - Computes the inverse of a complex Hermitian positive definite matrix A using the Cholesky factorization A = U**T*U or A = L*L**T computed by PLASMA_spotrf.
[in] | uplo | = PlasmaUpper: Upper triangle of A is stored; = PlasmaLower: Lower triangle of A is stored. |
[in] | N | The order of the matrix A. N >= 0. |
[in,out] | A | On entry, the triangular factor U or L from the Cholesky factorization A = U**T*U or A = L*L**T, as computed by PLASMA_spotrf. On exit, the upper or lower triangle of the (Hermitian) inverse of A, overwriting the input factor U or L. |
[in] | LDA | The leading dimension of the array A. LDA >= max(1,N). |
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. |
