Member Function Documentation

void sc::TwoBodyThreeCenterIntV3::compute_shell (int, int, int) [virtual]

Given three shell indices, integrals will be computed and placed in the buffer. The first two indices correspond to electron 1 and the second index corresponds to electron 2.

Implements sc::TwoBodyThreeCenterInt.

int sc::TwoBodyThreeCenterIntV3::log2_shell_bound (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.
