剑桥大学出版的英文matlab教材 高清晰(University of Cambridge, published in English teaching matlab)

使用有限元方法, 2D FEM计算热扩散方程. 三角形分割. (use of the finite element method, 2D FEM calculation of thermal diffusion equation. Triangle division.)

OFDM正交频分复用的基带系统，采用QPSK数字调制，统计系统的误码率(baseband of OFDM ，modulation by QPSK)

可以实现粒子群算法与盲源分离算法的结合，比较方便。源信号可以随便替换(PSO algorithm can be achieved with the combination of blind source separation algorithms, more convenient. Source signal can be easily replaced)

ACF中包含两个m文件，一个是自协方差函数（可单独使用）。另一个是自相关函数计算，其调用autocov函数。(ACF contains two m files, one is self-covariance function (which can be used alone). The other is calculated from the correlation function, which calls autocov function.)

MATLAB小程序，实现模糊仿人只能的仿真，和PID进行了对比(MATLAB applet, fuzzy imitation only simulation, and PID were compared)
