public interface MultivariateFunction {

    
Compute the value for the function at the given point.
Params:
point – Point at which the function must be evaluated.
Throws:
DimensionMismatchException – 
if the parameter's dimension is wrong for the function being evaluated.
MathIllegalArgumentException – 
when the activated method itself can ascertain that preconditions,
specified in the API expressed at the level of the activated method,
have been violated.  In the vast majority of cases where Commons Math
throws this exception, it is the result of argument checking of actual
parameters immediately passed to a method.
Returns:
the function value for the given point./**
