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
