3.5.5.3. scipy.interpolate.ppform¶

class scipy.interpolate.ppform(coeffs, breaks, fill=0.0, sort=False)[source]¶

Deprecated piecewise polynomial class.

New code should use the PPoly class instead.

__init__(coeffs, breaks, fill=0.0, sort=False)[source]¶

Methods

__init__(coeffs, breaks[, fill, sort])
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
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.
