Matlab小问题 问: Matlab仿真中怎样编辑Scope中的图象??? 答: 实现的方法有以下的几种: 1）PrintScreen，然后粘贴到Windows位图编辑器，选择图像点击右键，选择“反色”即可； 2）在Scope中，它的参数设置的第二页，有一个Save Data to Workplace，将它选中，然后在下面的方框 中指定变量名，然后用plot命令画出； 3）直接在模型上再加一个，to Workplace模块，也用plot画出； 4) 等scope显示出来图像以后，在matlab上运行 set(0, ShowHiddenHandles , On ) set(gcf, menubar , figure ) 这时候你会发现scope的工具栏的上面多了一行，点击insert-axes，鼠标会变成十字形状，然后再图像的任意一处双击左键出现一个对话框PropertyEditor，选中style在窗口的右便会出现color，这时你就可以任意修改背景颜色了。 问: 怎样进行S-function的编程和使用??? 答: S-function也就是System-function的缩写。说得简单，S-function就是用MATLAB所提供的模型不能完全满足用户，而提供给用户自己编写程序来满足自己要求模型的接口。要了(err)

试用时域最小平方误差准则（最小平方逆设计）设计一个具有四项系数的IIR DF的系统函数，使其在y(n)=[3,2,1]输入激励下，输出v(n)逼近d(n)=[2,0.2,0.05]。令v(-1)=v(-2)=0。求出v(n)的前8个样值与d(n)进行比较。用matlab实现了此要求。(trial at the least square error domain guidelines (minimum inverse square design) design with a four DF IIR coefficient of the system function, so in y (n) = [3,2,1] incentive to import, export v (n) approximation d (n) = [2,0.2,0.05]. So v (1) = v (2) = 0. Get v (n) of eight samples value d (n) comparisons. Using Matlab realization of this request.)
