        Simple constructor.
        Parameters:
        x - Sample values of the x-coordinate, in increasing order.
        y - Sample values of the y-coordinate, in increasing order.
        f - Values of the function on every grid point.
        dFdX - Values of the partial derivative of function with respect to x on every grid point.
        dFdY - Values of the partial derivative of function with respect to y on every grid point.
        d2FdXdY - Values of the cross partial derivative of function on every grid point.
        Throws:
        MathIllegalArgumentException - if the various arrays do not contain the expected number of elements.
        MathIllegalArgumentException - if x or y are not strictly increasing.
        MathIllegalArgumentException - if any of the arrays has zero length.
