Newton and Lagrange interpolating methods. It returns the polynomial of maximum degree given the set of centers.
var x = math.matrix([0.0, 1.2]); var y = math.matrix([1.0, 0.362358]); var f = Interpolate.newton(x, y); console.log(f(0.5))
var x = math.matrix([0.0, 1.2]); var y = math.matrix([1.0, 0.362358]); var f = Interpolate.lagrange(x, y); console.log(f(0.5))
