I need to be able to deal with functions like matlab

[romina]

Is there a variable type function in java? I need to be able to deal with functions like matlab does.
For example:

function x = "X^2";

Then evaluate the function at a point, for example:

x(10);

Is this possible?
Thanks.

What's wrong with doing:

public double f(double x) {
return x*x;
}

System.out.println(f(10));

Greetings.
