POTRF_STRIDED_BATCHED computes the Cholesky factorization of a batch of real symmetric (complex Hermitian) positive definite matrices.

(This is the blocked version of the algorithm).

The factorization of matrix \(A_i\) in the batch has the form:

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

\(U_i\) is an upper triangular matrix and \(L_i\) is lower triangular.

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 matrices A_i to be factored. On exit, the upper or lower triangular factors.
[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 factorization of matrix A_i. If info[i] = j > 0, the leading minor of order j of A_i is not positive definite. The i-th factorization stopped at this point.
[in]	batch_count	rocblas_int. batch_count >= 0. Number of matrices in the batch.
