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.
