%电影动画:
%1.首先调用moviein函数对内存初始化.创建一个足够大的矩阵来容纳一系列指定的图形(帧)
%2.调用getframe函数生成每一帧.该函数返回一个矢量,利用这个矢量创建一个电影动画矩阵
%3.调用movie函数按照指定速度进行指定次数的播放
%例子2:演示如何实现快速傅立叶变换(exp(j*2*pi/n))的可视化过程( Movie animation: 1. First transfers the moviein function to the
memory initialization Founds graph which an enough big matrix holds a
series of assigns (frame) % 2. Transfers the getframe function to
produce each This function returns to a vector, uses this vector to
found a movie animation matrix % 3. Transfers the movie function
according to assign the speed to carry on assigns the number of times
the broadcast
Example 2: How demonstrates realizes fast Fourier transforms
(exp (j*2*pi/n)) the visible process )
