POTRS_STRIDED_BATCHED solves a batch of symmetric/hermitian systems of n linear equations on n variables in its factorized forms.

For each instance j in the batch, it solves the system

\[ A_j X_j = B_j \]

where \(A_j\) is a real symmetric (complex hermitian) positive definite matrix defined by its triangular factor

\[ \begin{array}{cl} A_j = U_j'U_j & \: \text{if uplo is upper, or}\newline A_j = L_jL_j' & \: \text{if uplo is lower.} \end{array} \]

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 order of the system, i.e. the number of columns and rows of all A_j matrices.
[in]	nrhs	rocblas_int. nrhs >= 0. The number of right hand sides, i.e., the number of columns of all the matrices B_j.
[in]	A	pointer to type. Array on the GPU (the size depends on the value of strideA). The factor L_j or U_j of the Cholesky factorization of A_j returned by POTRF_STRIDED_BATCHED.
[in]	lda	rocblas_int. lda >= n. The leading dimension of matrices A_j.
[in]	strideA	rocblas_stride. Stride from the start of one matrix A_j to the next one A_(j+1). There is no restriction for the value of strideA. Normal use case is strideA >= lda*n.
[in,out]	B	pointer to type. Array on the GPU (size depends on the value of strideB). On entry, the right hand side matrices B_j. On exit, the solution matrix X_j of each system in the batch.
[in]	ldb	rocblas_int. ldb >= n. The leading dimension of matrices B_j.
[in]	strideB	rocblas_stride. Stride from the start of one matrix B_j to the next one B_(j+1). There is no restriction for the value of strideB. Normal use case is strideB >= ldb*nrhs.
[in]	batch_count	rocblas_int. batch_count >= 0. Number of instances (systems) in the batch.
