| void sc::TwoBodyIntV3::compute_shell | ( | 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.
Implements sc::TwoBodyInt.
| TwoBodyOperSet::type sc::TwoBodyIntV3::type | ( | ) | const [inline, virtual] |
Returns the type of the operator set that this object computes.
this function is necessary to describe the computed integrals (their number, symmetries, etc.) and/or to implement cloning.
Implements sc::TwoBodyInt.
