Here are some hints:
mxva is level 2 BLAS: matrix times vector
grid_orbital_values calculates values of the basis functions
(symmetry-adapted AOs) on the grid, and what you are seeing is the
transformation of that data through either the MO coefficients or the
If you want to see the density on the grid, you can simply do
