Detailed Description
GETRI_NPVT_OUTOFPLACE computes the inverse \(C = A^{-1}\) of a general n-by-n matrix A without partial pivoting.
The inverse is computed by solving the linear system
\[ AC = I \]
where I is the identity matrix, and A is factorized as \(A = LU\) as given by GETRF_NPVT.
- 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 = L*U returned by GETRF_NPVT.[in] lda rocblas_int. lda >= n.
Specifies the leading dimension of A.[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.
