QPSK信号在加入白高斯噪声（AWGN）后，用matlab进行仿真，并绘制了误码率图形。( The QPSK signal after joining the white gaussian noise (AWGN), carries on the simulation with matlab, and has drawn up the error rate graph. )

说明：  电气化铁路AT牵引网的谐波模型，调试成功!(AT electrified railway traction network harmonic model, debugging success!)

High Step-Up DC-DC Converters Using Zero-Voltage Switching Boost Integration Technique simulink model.

根据matlab的bvp4c函数的例子思想方法，求解特征值和特征函数，可以解变积分边界的问题，但是须给一个比较精确的初特征值。此为自编程序，已经标明注释。所附为bvp4c相关例子（此从matlab帮助文件节选）。(use the matlab solver bvp4c to obtain the both eigenvalues and eigenfunctions of BVPs, an exact initial eigenvalue is needed.)

Basic Continuous and Discrete Time functions

SINS和GPS组合导航，内包含程序，需要的数据，以及运行后得分析图等等。非常好，可以直接拿来用。(SINS and GPS navigation, and contains the program, the data needed, and post-run analysis chart and so on. Very good, can be directly used.)

系统辨识的模型阶次辨识，其中包括Hankel矩阵法，残差法，行列式法(System identification of model order identification, including Hankel matrix method, residual method, the determinant method)

说明：  基于MATLAB编程的行人检测，用的是SOBEL算法。(Pedestrian detection based on MATLAB)

说明：  离散信号处理举例，开发环境是MATLAB。(Discrete signal processing, for example, development environment is MATLAB.)

PSOt is different of PSOrt, because you can choose differents mode of convergence
