      • calculateJacobian

        public abstract DoubleMatrix calculateJacobian​(DoubleArray x)
        Calculate the Jacobian at a point $\mathbf{x}$. For a function $f: \mathbb{R}^m \to \mathbb{R}^n \quad x \mapsto f(x)$, the Jacobian is a n by m matrix.
        Parameters:
        x - the input vector $\mathbf{x}$
        Returns:
        the Jacobian $\mathbf{J}$
      • getLengthOfDomain

        public abstract int getLengthOfDomain()
        The length of the input vector $\mathbf{x}$.
        Returns:
        length of input vector (domain)
      • getLengthOfRange

        public abstract int getLengthOfRange()
        The length of the output vector $\mathbf{y}$.
        Returns:
        length of output vector (range)
