Detailed Description
POTRI inverts a symmetric/hermitian positive definite matrix A.
The inverse of matrix \(A\) is computed as
\[ \begin{array}{cl} A^{-1} = U^{-1} {U^{-1}}' & \: \text{if uplo is upper, or}\newline A^{-1} = {L^{-1}}' L^{-1} & \: \text{if uplo is lower.} \end{array} \]
where \(U\) or \(L\) is the triangular factor of the Cholesky factorization of \(A\) returned by POTRF.
- Parameters
-
[in] handle rocblas_handle. [in] uplo rocblas_fill.
Specifies whether the factorization is upper or lower triangular. If uplo indicates lower (or upper), then the upper (or lower) part of A is not used.[in] n rocblas_int. n >= 0.
The number of rows and columns of matrix A.[in,out] A pointer to type. Array on the GPU of dimension lda*n.
On entry, the factor L or U of the Cholesky factorization of A returned by POTRF. On exit, the inverses of A if info = 0.[in] lda rocblas_int. lda >= n.
specifies the leading dimension of A.[out] info pointer to a rocblas_int on the GPU.
If info = 0, successful exit for inversion of A. If info = j > 0, A is singular. L[j,j] or U[j,j] is zero.
