|Direct_Contraction (unsigned int nrow, unsigned int ncol, double scale)|
|Direct_Contraction (StateIn &si)|
|void||save_data_state (StateOut &so)|
|Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. |
|double||contract (const double *A, const double *B) const|
|Computes contraction of blocks A and B. |
Direct_Contraction is a straight scalar (dot) product of 2 rectangular blocks, scaled by scale.
Does the same as TwoParticleContraction but also scales the result.
