例3：分析占空比为ta的矩形脉冲频谱
T=1 时间窗大小
ta=0.5 占空比
N=256
t=linspace(-T,T,N)
ts=2*T/N
fs=1/ts
(x=zeros(1,N)
x(N/2-round(N/2*ta):N/2+round(N/2*ta))=ones(1,2*round(N/2*ta)+1)
y=fft(x,N)
figure
plot(t,x)
title([ 时域信号图 占空比为 ,num2str(ta)])
axis([-T T-0.2 1.2])
xlabel( t /s )
figure
subplot(211)
f=linspace(-fs/2,fs/2,N)
plot(f,abs(fftshift(y))/N)
title([ 矩形脉冲双边谱 脉冲时间t=[- ,num2str(ta*T), , ,num2str(ta*T), ] ])

matlab gui, 包括了4个很好的例子：
1.具有多个坐标轴的GUI，主要学习控制哪一个坐标轴是绘图命令的对象和用编辑文本框读入输入的数。
2.列表框目录阅读器，主要学习获取路径，加载，打开文件
3.从列表框中存取工作区变量，学习把存在于基本工作区的变量名放进列表框，选择多项等
4.地址簿阅读器，这个比较综合，用得技术也比较多。包括打开，保存，修改mat文件，利用handles结构保存和重新调用共享数据。(matlab gui, including four very good example: 1. with multiple axes of GUI, the main learning control which axis is the object of drawing commands and edit the text boxes with the number of read input. 2. The list box directory reader, the main study to obtain the path, load, open the file 3. From the variable list box to access the work area, learning the basic work area exists in the variable names into the list box, select a number of other 4 . address book readers, the more integrated, more technology used. Including open, save, modify mat file, save and re-use handles structure called shared data.)
