Radial Quadrature and Spectral Methods

Weights, nodes, and spectral methods matices for radial problems

Description

Computes the nodes and weights for numerically solving integrals of the form
 
   /R
   | f(r) r^k dr
   /0
 
on N grid points. Exact to machine precision for f(r) as a polynomial of
order 2N-1 or less. Constructs Vandermonde, Integration, and Differentiation matrices for radial differential equations.
