cholesky_decompose()

__kernel void stan::math::opencl_kernels::cholesky_decompose	(	__global double *	A,
		int	rows
	)

Calculates the Cholesky Decomposition of a matrix on an OpenCL.

This kernel is run with threads organized in one dimension and in a single thread block. The kernel is best suited for small input matrices as it only utilizes a single streaming multiprocessor. The kernels is used as a part of a blocked cholesky decompose.

Parameters

[in,out]	A	The input matrix and the result of the cholesky decomposition
	rows	The number of rows for A and B.

Note

Code is a const char* held in cholesky_decompose_kernel_code. Used in math/opencl/cholesky_decompose.hpp. This kernel uses the helper macros available in helpers.cl.
