Numerical integrator that uses Clenshaw-Curtis quadrature

Constructor & Destructor Documentation

Integrator()

marley::Integrator::Integrator

(

size_t

num = N_DEFAULT_

)

Create a Clenshaw-Curtis quadrature integrator that uses 2*num sampling points.

Parameters

num	half the number of sampling points to use

Todo:

add error check for when num == 0 or too small

Todo:

add error check for when num is ridiculously large
