## Detailed Description

GETRI_NPVT_OUTOFPLACE_BATCHED computes the inverse $$C_j = A_j^{-1}$$ of a batch of general n-by-n matrices $$A_j$$ without partial pivoting.

The inverse is computed by solving the linear system

$A_j C_j = I$

where I is the identity matrix, and $$A_j$$ is factorized as $$A_j = L_j U_j$$ as given by GETRF_NPVT_BATCHED.

Parameters
 [in] handle rocblas_handle. [in] n rocblas_int. n >= 0. The number of rows and columns of all matrices A_j in the batch. [in] A array of pointers to type. Each pointer points to an array on the GPU of dimension lda*n. The factors L_j and U_j of the factorization A_j = L_j*U_j returned by GETRF_NPVT_BATCHED. [in] lda rocblas_int. lda >= n. Specifies the leading dimension of matrices A_j. [out] C array of pointers to type. Each pointer points to an array on the GPU of dimension ldc*n. If info[j] = 0, the inverse of matrices A_j. Otherwise, undefined. [in] ldc rocblas_int. ldc >= n. Specifies the leading dimension of C_j. [out] info pointer to rocblas_int. Array of batch_count integers on the GPU. If info[j] = 0, successful exit for inversion of A_j. If info[j] = i > 0, U_j is singular. U_j[i,i] is the first zero pivot. [in] batch_count rocblas_int. batch_count >= 0. Number of matrices in the batch.
