Methods
__init__
(x, y, *args, **kwargs)Initialize self. 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_derivatives
(xi, yi[, orders, extrapolate])Construct a piecewise polynomial in the Bernstein basis, compatible with the specified values and derivatives at breakpoints. from_power_basis
(pp[, extrapolate])Construct a piecewise polynomial in Bernstein basis from a power basis polynomial. integrate
(a, b[, extrapolate])Compute a definite integral over a piecewise polynomial. roots
()Return the roots of the interpolated function. Attributes
