Polyutils
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.
Error objects
PolyError |
Base class for errors in this module. |
PolyDomainError |
Issued by the generic Poly class when two domains don’t match. |
Warning objects
RankWarning |
Issued by chebfit when the design matrix is rank deficient. |
Base class
PolyBase |
Base class for all polynomial types. |
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. |
