scipy.interpolate.ppform

class scipy.interpolate.ppform(coeffs, breaks, fill=0.0, sort=False)

Deprecated piecewise polynomial class.

New code should use the PPoly class instead.

Methods

__call__(x)
antiderivative([nu])	Construct a new piecewise polynomial representing the antiderivative.
construct_fast(c, x[, extrapolate, axis])	Construct the piecewise polynomial without making checks.
derivative([nu])	Construct a new piecewise polynomial representing the derivative.
extend(c, x[, right])	Add additional breakpoints and coefficients to the polynomial.
from_bernstein_basis(bp[, extrapolate])	Construct a piecewise polynomial in the power basis from a polynomial in Bernstein basis.
from_spline(tck[, extrapolate])	Construct a piecewise polynomial from a spline :Parameters: tck A spline, as returned by splrep extrapolate : bool, optional Whether to extrapolate to ouf-of-bounds points based on first and last intervals, or to return NaNs.
fromspline(xk, cvals, order[, fill])
integrate(a, b[, extrapolate])	Compute a definite integral over a piecewise polynomial.
roots([discontinuity, extrapolate])	Find real roots of the piecewise polynomial.
