Purpose

This module provides support for multivariate polynomials. Focus is on one-, two- and three-dimensional polynomials. Particular how to find an interpolating multivariate polynomial, evaluate its value at given points and finding the derivative of the polynomial. Below is an example usage of the module.

Example

import numpy as np
import isl.math.polynomial as POLY


x = np.rand.random(10,2)*10
v = np.rand.random(10,3)
order = 2
P0, P1, P2 = POLY.interpolate(order, x, v)

print(P1(x[10]))

dPdx, dPdy = POLY.derivative(P1)

print(dPdx)

output:

1 + x + y
