Dispatched C++ function(s).

[1] (grid: ndarray[complex, 1])
  -> ndarray[complex, 3]

[2] (grid: ndarray[complex, 1], theta: ndarray[complex, 3])
  -> ndarray[complex, 3]

[1] Evaluate the diagonal real-frequency Green’s function on a chosen grid.

[2] Evaluate the diagonal real-frequency Green’s function using Hardy-function optimization.

Parameters:

gridndarray[complex, 1]: Complex real-frequency grid (real frequency plus Lorentzian broadening).
thetandarray[complex, 3]: Hardy-function basis coefficients used to optimize the spectral function.

Returns:

ndarray[complex, 3]: Matrix-valued real-frequency Green’s function on the grid.
