自己的数字信号处理第三版的课后实验作业，有兴趣的可以参考参考。(Its own digital signal processing of the third edition of the after-school lab assignments, who are interested can refer to reference. !)

对Lorenze系统进行延迟反馈控制，系统采用Simulik建模仿真(Delay feedback Control for Lorenze Chaos system)

Matlab人工智能学习包，由世界领先的德国马普所制作(The spider is intended to be a complete object orientated environment for machine learning in Matlab. Aside from easy use of base learning algorithms, algorithms can be plugged together and can be compared with, e.g model selection, statistical tests and visual plots. This gives all the power of objects (reusability, plug together, share code) but also all the power of Matlab for machine learning research.)

共轭梯度法，优化算法的一种，具有二次收敛性，若目标函数为二次正定函数，经有限步可达到极小点(Conjugate gradient method, an algorithm with quadratic convergence, if the objective function is quadratic positive definite function can be achieved by the finite step minima)

七自由度汽车振动仿真模型建立，叙述了采用多刚体系统动力学建立汽车7自由度振动模型的方法，利用该模型对某汽车的平顺性进行研究。结果证明了该建模方法的正确性和数值计算的稳定性，同时也证明了设计结果的可行性。(seven dofs vehicle vibration)

This file describes about the working of BPSK MIMO OFDM system, here we are using two equalizing methods one based on matched filter and the other on MMSE and the relative comparison is done.

用matlab计算了一种弹簧的刚度，以及进行了线性回归(failed to translate)
