利用自相关法，计算基音周期，结果给出对应的时间值坐标。(The pitch period is calculated by the autocorrelation method, and the corresponding time value coordinate is given.)

simulated annealing 退货模拟算法实现(simulated annealing )

MATLAB 有约束信赖域算法，以四元多项式为算例 适用于学习最优化算法的数学专业学生以及其他数值分析课程的同学， 程序清晰，对MATLAB的学习也有很大的帮助，同时程序还有一些不足，读者自己须根据实际问题更正。(MATLAB constrained trust region algorithm to quaternion polynomial example for the application of optimization algorithms in the learning of mathematics students, as well as other courses in numerical analysis of the students, the program clearly and learning to MATLAB is also a great help, but the procedure also There are a number of shortcomings, the reader himself to be corrected in accordance with the actual problem.)

利用matlab来求解方程，包括13个程序例子和一个ppt(Using matlab to solve equations, including 13 program examples and a ppt)

说明：  MATLAB 代码 包括对scm 和scme信道的实现代码，附加端口说明(MATLAB code included scm and scme channel implementation code, additional port description)

MATLAB/Simulink通信系统建模与仿真中关于模拟调制信号的相关代码,包括AM,DSBSC,SSB,FM,FM的解调等代码.(MATLAB/Simulink communications system modeling and simulation of analog modulation signal code, including AM, DSBSC, SSB, FM, FM demodulation code.)

说明：  利用BP神经网络设计指纹识别算法，给神经网络提供每一模式类中的一些样本作为训练样本。BP网络经过学习，不仅能够识别已训练过的样本，而且能够识别未出现过的样本。利用神经网络的泛化能力，提高指纹识别算法的识别率，图像增强、提取指纹特征(BP neural network is the first mock exam to design fingerprint recognition algorithm, and it provides samples for each neural network as training samples. After learning, BP network can not only recognize the trained samples, but also recognize the samples that have not appeared. The generalization ability of neural network is used to improve the recognition rate of fingerprint recognition algorithm, image enhancement and fingerprint feature extraction)
