Polyutils — NumPy v2.4.dev0 Manual (original) (raw)
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.

| trimcoef(c[, tol]) | Remove "small" "trailing" coefficients from a polynomial. |
| getdomain(x) | Return a domain suitable for given abscissae. |
