Constructor & Destructor Documentation

gaulegh()

subroutine pesg::gaulegh::gaulegh	(	integer(spi), intent(in)	m,
		real(dp), dimension(m), intent(out)	x,
		real(dp), dimension(m), intent(out)	w )

This Gauss-Legendre quadrature integrates exactly any even polynomial up to degree m*4-2 in the half-interval [0,1].

This code is liberally adapted from the algorithm given in Press et al., Numerical Recipes.

Parameters

m	number of nodes in half-interval
x	nodes and weights
w	nodes and weights
