WebIntroduction. Cubic spline interpolation is the process of constructing a spline f: [x1, xn + 1] → R which consists of n polynomials of degree three, referred to as f1 to fn. A spline is a function defined by piecewise polynomials. Opposed to regression, the interpolation function traverses all n + 1 pre-defined points of a data set D. WebHessian matrix. In mathematics, the Hessian matrix or Hessian is a square matrix of second-order partial derivatives of a scalar-valued function, or scalar field. It describes …
