Member Function Documentation
◆ compute_shell()
|
virtual |
Given for shell indices, this will cause the derivative integral shell set to be computed.
- Parameters
-
[in] sh0 shell index for bra function of electron 1 [in] sh1 shell index for ket function of electron 1 [in] sh2 shell index for bra function of electron 2 [in] sh3 shell index for ket function of electron 2 [out] dercenters returns the information about centers the derivatives are computed for
Implements sc::TwoBodyDerivInt.
◆ log2_shell_bound()
|
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.
