Description: The cart with an inverted pendulum, shown below, is "bumped" with an impulse
force, F. Determine the dynamic equations of motion for the system, and lin
earize about the pendulum s angle, theta = Pi (in other words, assume that p
endulum does not move more than a few degrees away from the vertical, chosen
to be at an angle of Pi). Find a controller to satisfy all of the design re
quirements given below.

Description: ％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
