Constructs the explicit sum of Kronecker products of two matrices provided that they follow a fixed Kronecker product structure according to the corresponding sub-blocks. Imposing the latter condition is needed since this implementation requires that the given matrices have only one non-zero quantum number block for each row / block row Definition at line 635 of file DMRGKron.cpp. Referenced by DMRGBlockContainer< Block, Hamiltonian >::CalculateCorrelations_BlockDiag(). |
