Detailed Description

GETRI_NPVT inverts a general n-by-n matrix A using the LU factorization computed by GETRF_NPVT.

The inverse is computed by solving the linear system

$A^{-1}L = U^{-1}$

where L is the lower triangular factor of A with unit diagonal elements, and U is the upper triangular factor.

Parameters
 [in] handle rocblas_handle. [in] n rocblas_int. n >= 0. The number of rows and columns of the matrix A. [in,out] A pointer to type. Array on the GPU of dimension lda*n. On entry, the factors L and U of the factorization A = L*U returned by GETRF_NPVT. On exit, the inverse of A if info = 0; otherwise undefined. [in] lda rocblas_int. lda >= n. Specifies the leading dimension of A. [out] info pointer to a rocblas_int on the GPU. If info = 0, successful exit. If info = i > 0, U is singular. U[i,i] is the first zero pivot.
