| Abstract: | According to the matrix representation of quadric NURBS curve,for the(2n 1) data points of a curve,an interpolation algorithm based on quadric NURBS curve is presented with only the data points are made use of to solve control vertices.Efficiency of the algorithm has been demonstrated by numerical example. |
