||Return Pade approximation to a polynomial as the ratio of two polynomials.|
Return Pade approximation to a polynomial as the ratio of two polynomials.
- an : (N,) array_like
- Taylor series coefficients.
- m : int
- The order of the returned approximating polynomials.
- p, q : Polynomial class
- The Pade approximation of the polynomial defined by an is
>>> from scipy.interpolate import pade >>> e_exp = [1.0, 1.0, 1.0/2.0, 1.0/6.0, 1.0/24.0, 1.0/120.0] >>> p, q = pade(e_exp, 2)
>>> e_exp.reverse() >>> e_poly = np.poly1d(e_exp)
e_poly(x)and the Pade approximation
>>> e_poly(1) 2.7166666666666668
>>> p(1)/q(1) 2.7179487179487181
