Member Function Documentation void sc::TwoBodyDerivIntV3::compute_shell (int, int, int, int, DerivCenters &) [virtual] Given for shell indices, this will cause the integral buffer to be filled in. Implements sc::TwoBodyDerivInt. int sc::TwoBodyDerivIntV3::log2_shell_bound (int, int, int, int) [virtual] Return log base 2 of the maximum magnitude of any integral in a shell block. An index of -1 for any argument indicates any shell. Implements sc::TwoBodyDerivInt. Author Generated automatically by Doxygen for MPQC from the source code.
