etomica.math.numerical.PadeApproximation

public class PadeApproximation
extends java.lang.Object

Class to approximate a power series with rational function (Pade Approximation) Pade[K/L] = A_K/ C_L = B_M with Kth, Lth and Mth order, where K + L = M a0 + a1*x + a2*x^2 + ... + aK*x^K ---------------------------------- = b0 + b1*x + b2*x^2 + b3*x^3 + ... + b(K+L)*x^(K+L) [or bM*x^M] c0 + c1*x + c2*x^2 + ... + cL*x^L - c0 is set to be 1
