Detailed Description
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.
