Lagrange Interpolation

  var getLagrange = function(xInterpolationArray) {
    L = '';
    _.each(xInterpolationArray, function(dotActive, i) {
      if (i > 0) {
        L += '+';
      }
      L += '' + dotActive[1];
      _.each(xInterpolationArray, function(dot, j) {
        if (i != j) {
          L += '*((x-' + dot[0] + ') / (' + dotActive[0] + ' - ' + dot[0] + '))';
        }
      });
    });
    return L;
  }
