Detailed Description

GETRI inverts a general n-by-n matrix A using the LU factorization computed by GETRF.

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 = P*L*U returned by GETRF. On exit, the inverse of A if info = 0; otherwise undefined.
[in]	lda	rocblas_int. lda >= n. Specifies the leading dimension of A.
[in]	ipiv	pointer to rocblas_int. Array on the GPU of dimension n. The pivot indices returned by GETRF.
[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.
