现代信号处理大作业2-2，实现wv分布并画出3d图，指出了信号项和交叉项(2-2 large modern signal processing operations to achieve wv distribution and draw 3d map, pointing out items and cross-term signal)

用MATLAB编写的用BP网络完成函数的逼近源程序，希望有人用的上(MATLAB BP prepared by the network to be completed by the function approximation source, hoping that someone on the)

模拟实验室中产生的清音和浊音，通过仿真产生清浊音的频谱图，非常有效的对比，可以看出它们之间的差异。(Voiceless and voiced simulation laboratory generated by simulation generated Voicing the spectrum, very effective contrast, you can see the difference between them. )

Matlab能够通过sound函数来实现演奏歌曲，而且音调的高低是和频率有关，所以我们在进行音乐合成时需按音调来查所对应的频率，再按曲谱控制节奏长度，再利用sound函数播放由不同频率的正弦波合成的声音，于是就可以利用Matlab演奏歌曲了。(Music synthesis)

matlab带通滤波程序 两个滤波器都是切比雪夫I型数字滤波器，不是巴特沃尔滤波器，包括实例 (bandpass filtering matlab program)

粒子群算法求解机器人路径规划的MATLAB算法(the pathline of robot)

说明：  用matlab做的，而且有图片和解释。我用了2个小时写的，虽然不太好，还是可以供大家参考的。(using Matlab done, but pictures and explanation. I spent two hours writing, though not very good, or to be available for reference.)
