Function Documentation

int DSPF_dp_cholesky_in_place	(	const int	enable_test,
		const int	order,
		double *restrict	A
	)

This function tests the matrix A for a symmetric positive definite and decomposes the matrix A into a lower triangular matrix L where A=L*U and U=transpose of L. The processing is done in place of the matrix A. The values stored in the matrices are assumed to be double precision floating point values. This code is suitable for dense matrices. No optimizations are made for sparse matrices.

Parameters:

	enable_test	= enables test for symmetric positive definite matrix
	order	= order of matrix A
	A	= pointer to input matrix A and output matrix L

Algorithm:

DSPF_dp_cholesky_in_place.c is the natural C equivalent of the optimized intrinsic C code without restrictions. Note that the intrinsic C code is optimized and restrictions may apply.

Assumptions:

In-place processing is done on the matrix A.

Implementation Notes:

Interruptibility : The code is interruptible.
Endian support : supports both Little and Big endian modes.
