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]handlerocblas_handle.
[in]nrocblas_int. n >= 0.
The number of rows and columns of the matrix A.
[in]Apointer 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]ldarocblas_int. lda >= n.
Specifies the leading dimension of A.
[out]Cpointer to type. Array on the GPU of dimension ldc*n.
If info = 0, the inverse of A. Otherwise, undefined.
[in]ldcrocblas_int. ldc >= n.
Specifies the leading dimension of C.
[out]infopointer 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.
