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.
