In this directory, we can find the eleven files. The relationship between file name and the number of program written in the book is shown in as follows.

基于灰度梯度最大熵的分割方法，先通过聚类进行改进做初分割然后再进行细分割。(Segmentation of gray gradient based on maximum entropy, first through the clustering is improved. At first, then the fine segmentation segmentation.)

Lag compensator by the method of frequency response using Bode

用有限元分析的方法解微分方程，有限元计算过程中有个三角网格划分，这个程序就是关于三角形网格划分，(fem )

The good example for Solenoid Valve Control

threshold signcryption based on ecc

overlapped image segmentation the code can also be found at matlabcentral

BPSK解调中频偏检测器的设计与仿真,内含具体的PPT文档说明(BPSK demodulation frequency offset detector design and simulation, containing a specific PPT documentation)

自己编写的改进ELMAN网络辨识程序.非常实用(I have written procedures to improve the ELMAN network identification. Very useful)

• Plot the noisy speech signal both in time-domain and frequency-domain. • 进行含噪语音信号的时频分析 • Design a proper filter to remove noise from the speech signal. • 设计合适滤波器进行去噪 • Plot the clean signal both in time-domain and frequency-domain. • 进行去噪后信号的时频分析 • Design a Reverberator using 4 Comb filters and 2 All-pass filters, as shown in the following Figure, to generate reverberated and reflected sound with the capability of passing it through an equalizer. • 设计一个混响器（用四个梳状滤波器和两个全通滤波器（下图所示））来产生回声（通过一个均衡器（用于调整频率的补偿和衰减））
