It is mainly used for fingerprint recognition in matlab

stochastic geometry simulation matlab code: sp-program

基于混沌的模拟退火算法，采用偏最小二乘法，用蒙特卡洛模拟的方法计算美式期权的价格以及基本描述。( Chaos-based simulated annealing algorithm, Partial least squares method, Monte Carlo simulation method of calculating the American option price and basic description.)

基于matlab的BPSK的高斯白噪声调制解调 相信对大家有用(Based on matlab for BPSK modulation and demodulation of Gaussian white noise, I believe for all of us)

说明：  适用Otsu方法做阈值分析。阈值决策的依据是最大类间方差，这种方法的依据就是类间方差，本程序仅仅适用与二分类问题。(thresholding algorithm using Otsu)

灰色模型的源代码，很好用的，可以用来预测电力系统短期负荷(The source code of the gray model, well used, can be used to predict short term load)

network simulation of utms network

很实用的IPHONE完美实现自定义软键盘(IPHONE perfect realization of very useful custom keyboard)

用matalb进行ofdm的仿真，这个程序可以运行，简单明了(matalb used for the ofdm simulation, the process can run simple and clear)

语音是人类交换信息的有效渠道之一，也是我们日常生活交流的主要形式。 语音与当今科学技术的快速发展息息相关，特别是计算机中的语音交互技术，通 过对语音信号进行采集和处理，实现人与人之间有效信息的传输、获取以及存储。 基于 MATALAB 的语音信号去噪设计，对噪声信号进行有效地滤除，将降噪后的语音信号与原始 信号在时域和频域进行对比分析，计算出信噪比，并在 MATLAB 中设计 GUI 仿 真界面进行展示.(Speech is one of the effective ways for human to exchange information, and it is also the main form of our daily life communication. Speech is closely related to the rapid development of modern science and technology, especially the voice interaction technology in the computer. Through the acquisition and processing of voice signals, the transmission, acquisition and storage of effective information between people and people is realized. Based on the noise signal de-noising design of MATALAB, the noise signal is effectively filtered, the speech signal and the original signal after the noise reduction are compared and analyzed in the time domain and frequency domain, and the signal to noise ratio is calculated, and the GUI simulation interface is designed in the MATLAB.)
