title: How can i produce multi point linear interpolation?
body: <p>I have a linear interpolation methods. This is calculate interpolate value when (x1,y1) (x2,y2) and x0 known. it is calculate y0 value. But i need the do that when multi point known.</p>
  
  <p>I am not talking about Bilinear or Trilinear interpolation.</p>
