一个很有用的程序，音频信号通过LM386放大，小波包分析提取振动信号中的特征频率。( A very useful program, LM386 audio signal amplification, Wavelet packet analysis to extract vibration signal characteristic frequency.)

说明：  1.编制一个计算两个序列线性卷积的程序，计算y(i)=x(m)*h(n)，分别绘制x(m)和h(n)，以及线性卷积结果y(i)的图形，使用matlab自带的conv函数来验证结果。 2.使用matlab自带的FFT和iFFT程序，实现线性卷积的快速计算，并对计算结果进行绘制。(1. Make a program to calculate the linear convolution of two sequences, calculate y (I) = x (m) * H (n), draw the graph of X (m) and H (n), and the graph of the linear convolution result y (I), and use the conv function of MATLAB to verify the result. 2. The FFT and IFFT programs of MATLAB are used to realize the fast calculation of linear convolution and draw the calculation results.)

MATLAB 7简明教程讲义及源代码 在这个论坛里得到了很多人的帮助，也学到了很多东西。发点东西让更多的人得到进步和提高！！ (MATLAB 7 simple tutorial notes and source code in this forum have helped many people, but also learned a lot. Send something to let more people get progress and improve! !)

Matlab不仅具有强大的数值运算功能，也同样具有非常强大的二维和三维图形绘制功能，尤其擅长于将各种科学运算结果的可视化。计算的可视化可以将不直观的数据通过图形来表示，从而发现其中的内在关系。Matlab的图形命令格式简单，可以使用不同的线形，色彩、数据点标记和标注等来修饰(Graphic Design)
