====================
Electronic Integrals
====================

The constructor functions listed here generally take the coefficients of
electronic structure Hamiltonians as an input. Different flavors exist:

* ``tril``: these functions consume 1-dimensional arrays of flattened
  (generalized) triangular indices
* ``full``: these functions consume high-dimensional arrays
* ``spin``: these functions take separate arrays for the different spin species
* ``sym``: these functions take a single array for one spin species and infer
  the other spin species
