Detailed Description

template<class mp_real>
class QuantLib::GaussLaguerreSinePolynomial< mp_real >

Gauss-Laguerre Sine integration.

This class performs a 1-dimensional Gauss-Laguerre-Cosine integration.

\[ \int_{0}^{\inf} f(x) \mathrm{d}x \]

The weighting function is

\[ w(x;u)=e^{-x}*\sin{u*x} \]
