Piecewise polynomial curve specified by points and derivatives
This class represents a curve that is a piecewise polynomial. It passes through a list of points and has specified derivatives at each point. The degree of the polynomial may very from segment to segment, as may the number of derivatives available. The degree should not exceed about thirty.
Appending points to the end of the curve is efficient.
Methods
__call__(x) | Evaluate the piecewise polynomial |
append(xi, yi[, order]) | Append a single point with derivatives to the PiecewisePolynomial |
derivative(x, der) | Evaluate a derivative of the piecewise polynomial |
derivatives(x, der) | Evaluate a derivative of the piecewise polynomial |
extend(xi, yi[, orders]) | Extend the PiecewisePolynomial by a list of points |
