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.
