Detailed Description

Gauss-Legendre (l,m,n)-p Scheme.

Parameters

l	order of Gauss-Legendre integration within every fixed point iteration step
m	fixed point iteration steps, first step is a partial Jacobi-Newton, the rest are naive Richardson fixed point iterations
n	number of Chebyshev nodes to interpolate the exercise boundary
p	order of Gauss-Legendre integration in final conversion of the exercise boundary into option prices
