【Abstract】 Based on the B-spline compactly supported scaling function,this paper constructs a 2-regular smooth interpolating function with compact support, show that it satisfies the Strang-Fix condition and Riese condition,Therefore, it has a good approximation performance. Finally, the paper gives a simple and fast algorithm for generating the relatively complex curves without any truncated errors except the finite digital length errors.更多还原
