Additional Inherited Members¶

sc::mPW91XFunctional::mPW91XFunctional (Func variant)¶

Construct an mPW form exchange functional using the given functional variant. The variant can be B88, PW91, or mPW91.

sc::mPW91XFunctional::mPW91XFunctional (const Ref< KeyVal > &)¶

Construct an mPW form exchange functional. The following keywords are recognized:

constants

This can be B88 to give the Becke88 exchange functional; PW91, to give results similar to the PW91 exchange functional; or mPW91, to give the new functional developed by Adamo and Barone.

b

beta

c

d

x_d_coef

The coefficient of $x^d$, where $x$ is the reduced gradient.

void sc::mPW91XFunctional::save_data_state (StateOut &) [virtual]¶

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. This must be implemented by the derived class if the class has data.
