Detailed Description

POTRI_BATCHED inverts a batch of symmetric/hermitian positive definite matrices \(A_i\).

The inverse of matrix \(A_i\) in the batch is computed as

\[ \begin{array}{cl} A_i^{-1} = U_i^{-1} {U_i^{-1}}' & \: \text{if uplo is upper, or}\newline A_i^{-1} = {L_i^{-1}}' L_i^{-1} & \: \text{if uplo is lower.} \end{array} \]

where \(U_i\) or \(L_i\) is the triangular factor of the Cholesky factorization of \(A_i\) returned by POTRF_BATCHED.

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_i.
[in,out]	A	array of pointers to type. Each pointer points to an array on the GPU of dimension lda*n. On entry, the factor L_i or U_i of the Cholesky factorization of A_i returned by POTRF_BATCHED. On exit, the inverses of A_i if info[i] = 0.
[in]	lda	rocblas_int. lda >= n. specifies the leading dimension of A_i.
[out]	info	pointer to rocblas_int. Array of batch_count integers on the GPU. If info[i] = 0, successful exit for inversion of A_i. If info[i] = j > 0, A_i is singular. L_i[j,j] or U_i[j,j] is zero.
[in]	batch_count	rocblas_int. batch_count >= 0. Number of matrices in the batch.
