与奥本海姆 的《信号与系统》经典教材配套的习题解哦(Solution Oh Oppenheim " Signals and Systems" classic textbook exercises supporting)

编写M文件，创建如下图形窗口，分别绘制如下图所示的曲线。 （1）曲线y=sin(t)sin(9t)，要求采用红色，点线。横坐标取值范围[0~ ]，标注x轴、y轴并加标题。 （2）一组余弦曲线，其振幅分别为0.4，0.6和0.8。横坐标取值范围[0~2 ]。添加图例与标题。进入图形编辑状态，调整图例的位置。 （3）分别绘制peaks函数的曲面图和网格线图。对曲面图做平滑处理，并添加标题与colorbar。 (Write M file, create the following graphics window, curves were plotted as shown below. (A) the curve y = sin (t) sin (9t), require the use of a red dotted line. The abscissa in the range [0 ~  ], labeled x-axis, y-axis and a title. (2) a set of a cosine curve, and the amplitude was 0.4, 0.6, 0.8. Abscissa value range [0 ~ 2  ]. Add a legend and title. Into the graphical editing mode, adjust the position of the legend. (3) were drawn surface chart peaks function and grid line graph. Surface charts do for smoothing and add titles and colorbar.)

利用四阶龙格-库塔的数值方法编程实现传递函数(transfer function accomplishment)

说明：  遗传算法matlab工具 1.工具箱文件拷贝至Matlab文件夹下，具体路径为：C:\program files\MATLAB\R2009a\toolbox。 2.工具箱路径加入Matlab文件路径之中。 流程为：File-->Set Path-->Add Folder。即，将C:\program files\MATLAB\R2009a\toolbox\文件夹加入该路径系统中。 3 重新启动Matlab，运行即可。 4 一般情况下，会出现如下情况。 安装遗传工具箱后出现问题：Warning: Name is nonexistent or not a directory: \afs\eos\info\ie\ie589k_info 解决方案： 将C:\program files\MATLAB\R2009a\toolbox\文件夹下的startup.m文件中的路径“\afs\eos\info\ie\ie589k_info\”改为goat当前所在的目录，“C:\program files\MATLAB\R2009a\toolbox\”即可。(Genetic algorithm matlab tool 1. Matlab toolbox files are copied to the folder, the specific path is: C: \ program files \ MATLAB \ R2009a \ toolbox. 2. Matlab toolbox add the file path into the path. Process is: File-&gt Set Path-&gt Add Folder. That is, the C: \ program files \ MATLAB \ R2009a \ toolbox \ folder by adding the path system. 3 Restart Matlab, can be run. 4 Under normal circumstances, there will be the following. Problems after installing genetic toolbox: Warning: Name is nonexistent or not a directory: \ afs \ eos \ info \ ie \ ie589k_info \ Solution: C: \ program files \ MATLAB \ R2009a \ toolbox \ startup folder under the . m file path &quot \ afs \ eos \ info \ ie \ ie589k_info \&quot to the current directory where the goat, &quot C: \ program files \ MATLAB \ R2009a \ toolbox \&quot can be.)
