Utility classes and functions for the polynomial modules.

This module provides: error and warning objects; a polynomial base class; and some routines used in both the polynomial and chebyshev modules.

Functions

as_series(alist[, trim])	Return argument as a list of 1-d arrays.
trimseq(seq)	Remove small Poly series coefficients.
trimcoef(c[, tol])	Remove "small" "trailing" coefficients from a polynomial.
getdomain(x)	Return a domain suitable for given abscissae.
mapdomain(x, old, new)	Apply linear map to input points.
mapparms(old, new)	Linear map parameters between domains.
