    • Method Detail

      • evaluate

        public Double evaluate​(Vector y)
        Description copied from interface: Function
        Evaluate the function f at x, where x is from the domain.
        Parameters:
        y - x
        Returns:
        f(x)
      • dimensionOfDomain

        public int dimensionOfDomain()
        Description copied from interface: Function
        Get the number of variables the function has. For example, for a univariate function, the domain dimension is 1; for a bivariate function, the domain dimension is 2.
        Returns:
        the number of variables
      • dimensionOfRange

        public int dimensionOfRange()
        Description copied from interface: Function
        Get the dimension of the range space of the function. For example, for a Rn->Rm function, the dimension of the range is m.
        Returns:
        the dimension of the range
