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.
