用matlab实现了2dpca算法，基于ORL人脸数据库，识别率较高(Matlab achieved with 2dpca algorithm, based on the ORL face database, the higher recognition rate)

说明：  计算任一语音信号的短时自相关函数，并用画图的形式表现出来，可自定义样本数，和采样频率。方便简洁。(Any calculation of short-time speech signal autocorrelation function, and use the form of drawing out the number of samples can be customized, and the sampling frequency. Easy to clean.)

D:matlab mmeigen.rar特征值(D : Matlab nmm eigen.rar eigenvalue)

in this package are the programs needed to solve any initial value differential problem.

稀疏编码在图像分类中的实现,自己写的matlab程序，带demo(sparsecoding in image classification)

基于增广矩阵束的L型阵列的二维DOA估计MATLAB程序(Based on the augmented matrix L-shaped beam two-dimensional array DOA estimation MATLAB program)

matlab的gscale函数功能是将强度图像等映射到别的值范围。(Function of matlab gscale intensity images is mapped to another range.)

元胞自动机模拟交通流程序，学校交通专业学长给的，能够模拟单车种双车道交通流变化，考虑驾驶员行为。做数学建模美赛的时候用到。(Cellular automaton simulation of traffic flow program, school traffic professional senior, can simulate the change of bike traffic flow, consider driver behavior.)

设计一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(Designed a four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)
