## 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.
