Detailed Description
POTRI_STRIDED_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_STRIDED_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 pointer to type. Array on the GPU (the size depends on the value of strideA).
On entry, the factor L_i or U_i of the Cholesky factorization of A_i returned by POTRF_STRIDED_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.[in] strideA rocblas_stride.
Stride from the start of one matrix A_i to the next one A_(i+1). There is no restriction for the value of strideA. Normal use case is strideA >= lda*n.[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.
