| Abstract: | The solution to the problem of curve deformation by the linear transformation of sampling data is put forward. The algorithm based on the Lagrange interpolation is designed. The complexity of the algorithm is discussed. The deformation method is researched in details. The result can be used to carry out the deformation of algebraic curves. The feasibility and validity of the algorithm is demonstrated by numerical experiment. The practice has proved that it provided an efficient approach to the problem of curve deformation. |
