I don't think so: you are expected to carry out the numerical
integration yourself. (There may be some scripts that do this, but I
highly recommend that, at least at the beginning, you do this step
yourself, so that you are sure what is going on.

You could run a Google search on "Gaussian quadrature". But by the time
you get to 20 to 30 points, you probably can just use equally-spaced
lambdas.
