compute_2e_matrix_simple computes the 2el matrix in the simplest possible way.

It assumes that the matrix is computed for closed shell. The weight of the HF exchange is controlled by

Parameters:

hf_weight	which is equal 1 for ordinary Hartree-Fock calculation. No assumption are made regarding symmetry of the density matrix
dens	. The computed two-electron part of the Fock matrix is returned in
result	.
basisInfo	info about the used basis set.
integralInfo	info needed for evaluation of integrals of Gaussian functions.
