Polynomial Module (numpy.polynomial.polynomial)
New in version 1.4.0.
This module provides a number of objects (mostly functions) useful for
dealing with Polynomial series, including a Polynomial 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).
Polynomial Class
| Polynomial(coef[, domain, window]) |

|
| polyroots(cs) |
Compute the roots of a polynomial. |
| polyfromroots(roots) |

Fitting
| polyfit(x, y, deg[, rcond, full, w]) |
