Detailed Description

POTRF computes the Cholesky factorization of a real symmetric (complex Hermitian) positive definite matrix A.

(This is the blocked version of the algorithm).

The factorization has the form:

\[ \begin{array}{cl} A = U'U & \: \text{if uplo is upper, or}\newline A = LL' & \: \text{if uplo is lower.} \end{array} \]

U is an upper triangular matrix and L is lower triangular.

Parameters
[in]handlerocblas_handle.
[in]uplorocblas_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]nrocblas_int. n >= 0.
The number of rows and columns of matrix A.
[in,out]Apointer to type. Array on the GPU of dimension lda*n.
On entry, the matrix A to be factored. On exit, the lower or upper triangular factor.
[in]ldarocblas_int. lda >= n.
specifies the leading dimension of A.
[out]infopointer to a rocblas_int on the GPU.
If info = 0, successful factorization of matrix A. If info = j > 0, the leading minor of order j of A is not positive definite. The factorization stopped at this point.
