19 Jun 2013 2D Barycentric Lagrange Interpolation Interpolates a function on a rectangle. Author: Greg von Winckel Alessandra

Hello! It 's the first time I write on the site. This feature I really like and I think I can be of help for the thesis I am doing. I would like to know if someone could help me to understand the inputs. What is f? xn? yn? xf? yf?
Thank you very much!

27 Feb 2013 Gauss Quadrature for Tetrahedra Compute Gauss weights and nodes for a specied tetrahedron Author: Greg von Winckel yj2011

Work wonderfully. One question. Not quite understand the Gauss Quadrature, but I noticed that the code by default outputs 64 note points. Can I increase the number of note points in order to improve the integration results?

Good and very helpful..
14 Jul 2012 Bessel Function Zeros Computes the first k zeros of the Bessel Function of the 1st and 2nd Kinds. Author: Greg von Winckel Pettres, Roberto

Utilizei a rotina para calcular a solução analítica da equação da difusão 2D. Ficou muito boa.
