Solution

2007年全国大学生数学建模获奖论文所需程序代码，其中有较详细的matlab编程，应该有些用处吧(Mathematical Contest in Modeling 2007, papers required for award-winning code, including more detailed matlab programming, it should be of some use)

参数自整定PI估计器在永磁同步电机直接转矩控制中的应用研究的硕士论文。很有参考价值。(Parameter self-tuning PI estimator in the permanent magnet synchronous motor direct torque control of the applied research, Vol. Great reference value.)

Link stability in matlab

说明：  资料为基于BP基于BP神经网络的人脸识别源码（matlab），是课程设计做的一个课题，效果还不错，配备有测试显示界面，比较直观！(The data is the source code of face recognition based on BP neural network (matlab), which is a subject of curriculum design. The effect is good, equipped with test display interface, which is more intuitive!)

Butterworth hih/low and band pass filters are applied to image

说明：  这是用MATLAB 编写的有关各种PID控制器的程序，非常的全，非常的有效。(MATLAB prepared by the various procedures PID controller, the whole very, very effective.)

qpsk的调制解调源码，注释详细。功能正常。很适合学习调制解调的人.文件包含： qpsk_mod_demod.m(qpsk mod and demod procedure qpsk_mod_demod.m)

本程序可计算主应力大小和方向。主应力就是两个垂直方向的作用力的合力所产生的力在单位截面上的力。(This program can calculate principal stress size and direction. Two vertical principal stress is the force by the force of the force in the direction of force on cross section in the unit.)

目标跟踪仿真小程序，本程序简单易懂适合初学者学习和参考。(Small target tracking simulation program, the program simple and easy to understand for beginners learning and reference.)
