Member Function Documentation

void sc::TwoBodyIntV3::compute_shell	(	int	,
		int	,
		int	,
		int
	)		`[virtual]`

Given four shell indices, integrals will be computed and placed in the buffer.

The first two indices correspond to electron 1 and the second two indices correspond to electron 2.

int sc::TwoBodyIntV3::log2_shell_bound	(	int	,
		int	,
		int	,
		int
	)		`[virtual]`

Return log base 2 of the maximum magnitude of any integral in a shell block obtained from compute_shell.

An index of -1 for any argument indicates any shell.
