Gauss-Laguerre quadrature Calculator

Calculates the integral of the given function f(x) over the interval (0,∞) using Gauss-Laguerre quadrature.


Gauss-Laguerre quadrature
α
    1. partition n
    2. n=2,3,4,..,100

The integrand f(x) is assumed to be analytic and non-periodic.

    Comment/Request
    I have two function in double integral from 0 to infinity and I already use Gauss-Laguerre to solve one of them . But Now I have double integral in the form

    int int (F(M) dM * F(p,M) dP)

    I want to repeat Gauss lageuerre or recall it to solve the integral that remains after the first integral over p then it remains a function over M multiplied by F(M). How can I do that.

    I have to put it in C-language
