public static double polyval(double x, double[] coeff) throws ArithmeticException
y = coeff[0]*x^n + coeff[1]*x^(n-1) + .... + coeff[n-1]*x + coeff[n].
E.g. for a quadratic function, y = coeff[0]*x^2 + coeff[1]*x + coeff[2].
x
- argument to the polynomial.coeff
- the coefficients of the polynomial.
