Detailed Description

Calculation of the Gaussian Product Theorem terms.

Function Documentation

mirp_gpt()

void mirp_gpt	(	const arb_t	alpha1,
		const arb_t	alpha2,
		arb_srcptr	A,
		arb_srcptr	B,
		arb_t	gamma,
		arb_ptr	P,
		arb_ptr	PA,
		arb_ptr	PB,
		arb_t	AB2,
		slong	working_prec
	)

Computes terms from the Gaussian Product Theorem using interval arithmetic.

The input parameters A and B, are expected to be arrays of 3 elements.

The output parameters P, PA, and PB are also expected to be arrays 3 elements.

See Gaussian Product Theorem

[out]	gamma	Combined exponent (alpha1 + alpha2)
[out]	P	Coordinates of the new gaussian
[out]	PA	XYZ distances between the new gaussian and the first gaussian
