This module provides a number of objects (mostly functions) useful for dealing with Laguerre series, including a Laguerre class that encapsulates the usual arithmetic operations. (General information on how this module represents and works with such polynomials is in the docstring for its ?parent? sub-package, numpy.polynomial).
Laguerre Class
Laguerre(coef[, domain, window]) | A Laguerre series class. |
Basics
lagval(x, c[, tensor]) | Evaluate a Laguerre series at points x. |
lagval2d(x, y, c) | Evaluate a 2-D Laguerre series at points (x, y). |
lagval3d(x, y, z, c) | Evaluate a 3-D Laguerre series at points (x, y, z). |
laggrid2d(x, y, c) | Evaluate a 2-D Laguerre series on the Cartesian product of x and y. |
laggrid3d(x, y, z, c) | Evaluate a 3-D Laguerre series on the Cartesian product of x, y, and z. |
lagroots(c) | Compute the roots of a Laguerre series. |
lagfromroots(roots) | Generate a Laguerre series with given roots. |
Fitting
lagfit(x, y, deg[, rcond, full, w]) | Least squares fit of Laguerre series to data. |
