Method Detail

getPolynomial

public static Polynomial getPolynomial(int n)

Gets the n-th Hermite polynomial. If it has already been calculated it just returns it from the list. If we have not calculated it uses the recursion relationship to construct the polynomial based on the prior polynomials.

evaluate

public static double evaluate(int n,
              double x)

Evaluates the n-th Hermite polynomial at x.

Returns:

the value of the function
