DSP
任务:
1) 借助MATLAB画出误差性能曲面和误差性能曲面的等值曲线(参考PPT2.1第17页的两幅图);
2) 写出最陡下降法以及LMS算法的计算公式(取 );
3) 用MATLAB产生方差为0.05, 均值为0白噪音S(n),并画出某次采样得到的波形(即产生任意一个噪声随机序列);
4) 根据 2)中的公式,并利用 3)中产生的S(n),在 1)中的误差性能曲面的等值曲线上叠加画出采用最陡下降法以及LMS法时H(n)的在叠代过程中的轨迹曲线(参考PPT2.1第17页的右下图的曲线1和曲线2)。
5)用MATLAB计算并画出LMS法时 随时间n的变化曲线(对应S(n)的某一次的一次实现)和e(n)波形;
注意:某一次实现的结果并不能从统计的角度反映实验的结果 的正确性,为得到具有统计特性的实验结果,可用足够多次的 实验结果的平均值作为实验的结果。用MATLAB计算并画出 采用LMS法时,J(n)的100次实验结果的平均值随时间n的变 化曲线(即 生成随机噪声信号并计算结果,重复执行100次, 求平均结果)。
6)在 1)中的误差性能曲面的等值曲线上,叠加画出采用LMS法得到的100次实验中的H(n)的平均值的轨迹曲线;
(Task:
1 ) Draw with MATLAB error performance surface and surface contour error performance curve ( refer PPT2.1 two chart on page 17 )
2 ) Write the steepest descent method and the LMS algorithm formula ( take )
3 ) Using MATLAB to generate variance of 0.05 with a mean of 0 white noise S (n), and draw a particular sampling waveform ( ie, any noise generated random sequence )
4 ) based on 2 ) of the formula , and use 3 ) generated in S (n), in a ) the error performance curves superimposed on the surface contour plot using the steepest descent method and the LMS method when H (n) the iterative process in the trajectory curve ( refer PPT2.1 page 17 bottom right of the curves 1 and 2 ) .
5 ) using MATLAB LMS method is used calculate and draw the curve with time n (corresponding to S (n) of a first implementation of a ) and e (n) waveform
Note : in a first implementation of the results are not reflected from a statistical point of view of accuracy of the experimental results ,)

kmltoolbox_v1.4
基于这个类的工具箱允许你创建在“Google地球”,许多不同的地块,由自动创建所需的基于XML的KML文件,而无需用户交互。
有了它,您可以创建:
- 线图,散点图
- 二维和三维轮廓
- 2D和3D多边形
- 颤动地块
- 写在一个特定点的文本
- 将三维模型
- 覆盖图像
- 为图像传输更复杂的数字
- 文件夹,子文件夹,... 总相似图
- 动画三维模型到一个预定义的轨迹
安装到您的MATLAB路径工具箱,工具箱目录,并运行:
>> kml.install
现在,每个功能和可用的参数文件。要查看帮助,在MATLAB中运行:
>> kmldoc
或
>> kmldoc kml.plot%或任何其他可用的地块
如果你喜欢它,只是给我发电子邮件在说什么你使用它:) kml@rafael.aero。
灵感来自于原来的Google地球工具箱,但使用XML对象实现的,这使得它更容易使用。我只是检查在MATLAB 2011a释放,但它应该在旧版本的工作太... (让我知道如果不!)(Based on this class allows you to create a" toolbox in Google earth", many different plots, created automatically by the XML based on the KML file, without the need for user interaction.
With it, you can create:
- line graphs, scatter diagram
-2D and 3D contour
- 2D and3D polygon
- fibrillation plots
- written at a particular point in the text
- the three-dimensional model
- cover image
For more complex digital image transmission
Folder, subfolders, total similarity graph ...
- Animated3D model into a predefined trajectory
Install to your path to the MATLAB toolbox, toolbox directory, and run:
> > kml.install
Now, each function and the available parameter file. To view the help, running in the MATLAB:
> > kmldoc
Or
> > kmldoc kml.plot or any other available plots
If you like it, just email me say in what you use it ): kml@rafael.aero.
Inspiration from the original Google earth toolbox, but using the XML object is achieved, which makes it easier to )
