DerivativeStructure value(DerivativeStructure[] point)
```
    Compute the value for the function at the given point.
    
    Parameters:
    
    point - Point at which the function must be evaluated.
    
    Returns:
    
    the function value for the given point.
    
    Throws:
    
    MathIllegalArgumentException - if point does not satisfy the function's constraints (wrong dimension, argument out of bound, or unsupported derivative order for example).
