Synopsis

atom_diag::op_block_mat_t get_op_mat (atom_diag::many_body_op_t const & op) const

Get block matrix representation for general operator

Parameters

• op Many body operator

Returns

The block matrix representation of the operator (in the Hamiltonian eigen basis)

Throws, in case the provided operator does not respect the block symmetries used in the diagonalization.
