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.

Implements sc::TwoBodyInt.

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.
