## Detailed Description

GETRI_OUTOFPLACE computes the inverse $$C = A^{-1}$$ of a general n-by-n matrix A.

The inverse is computed by solving the linear system

$AC = I$

where I is the identity matrix, and A is factorized as $$A = PLU$$ as given by GETRF.

Parameters
 [in] handle rocblas_handle. [in] n rocblas_int. n >= 0. The number of rows and columns of the matrix A. [in] A pointer to type. Array on the GPU of dimension lda*n. The factors L and U of the factorization A = P*L*U returned by GETRF. [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] C pointer to type. Array on the GPU of dimension ldc*n. If info = 0, the inverse of A. Otherwise, undefined. [in] ldc rocblas_int. ldc >= n. Specifies the leading dimension of C. [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.
