# 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.

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 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 the piecewise polynomial. solve([y, discontinuity, extrapolate]) Find real solutions of the the equation pp(x) == y.
