用粒子群算法PSO优化BP神经网络，改善预测精度(The BP neural network is optimized by particle swarm optimization (PSO) to improve the prediction accuracy)

用MATLAB小波工具箱实现的信号奇异点的检测(MATLAB toolbox realize the singular point of the signal detection)

MATLAB工具函数汇总。对参加数学建模用MATLAB写程序很有帮助(matlab utility functions summary。)

jx Robot源码，需要的可以看看,互相学习(jx Robot source, need to look at)

This is a Matlab function that calculates the band structure for an one dimensional structure by means of PWE method. you will see more details about using it insid the file.

在MATLAB的simulate工具箱中直流电机的速度PID控制(Toolbox in MATLAB' s simulate the speed of DC motor PID control)

WCDMA的simulink编程与开开发，相对来说比较详细，找的比较辛苦。 (WCDMA in simulink programming and open development, is relatively detailed, and looking hard.)

信号与系统matlab作业，实现卷积操作，供学习信号与系统的同学们参考(1. Define two signals as: x1[n] =   n, 0 < n  N1+1 2 N1 − n+ 1, N1+1 2 < n  N1 0, elsewhere and x2[n] =  1, 0 < n  N2 0, elsewhere We let N1 = 999 and N2 = 500. (a) (30 )Write a MATLAB function myconv to compute x1[n]x2[n] where  denotes the convolution sum. You have to plot your result and attach it in your report. You may use the MATLAB function conv to check whether your result is correct.)
