用复傅立叶变换绘制曲线形成的任意图形。

An arbitrary diagram formed by a curve is drawn by a complex Fourier transform. 

通过结合傅立叶变换得到的向量，重现曲线上的构成点。

The points on the curve are reproduced by combining the vectors obtained by the Fourier transform. 

由于傅立叶变换的复数特性，所有的矢量都表现为匀速圆周运动。

Because of the complex Fourier transform, all vectors are in constant velocity circular motion.

原始曲线坐标必须存储在.mat文件中

** Original curve coordinates must already be stored in a.mat file **
