Library for polynomial calculus in Java? [closed]

Question

Are there any (preferably open source) library for Java that allows one to do calculus with polynomial e.g. addition, multiplying, dividing by constans etc. ?

Also if it would be capable to interpolate several 2D points in a polynomial with Lagrange polynomial interpolation, it will be a plus.

Answer 1

You might want to have a look at the Apache Commons Mathematics Library.

Polynomials are handled with PolynomialFunction and you can do a Lagrange interpolation with PolynomialFunctionLagrangeForm
