DM6_decision_tree

用Matlab仿真了对称阵子的方向图，阻抗特性和辐射阻抗(The stream of Matlab simulation with the direction of the symmetric map, impedance characteristics and radiation impedance)

一个用simulink做的模糊PID自适应系统，通过三个模糊FIS：dkp,dki,dkd来分别控制Kp,Ki,Kd，以达到PID参数可自动调整的目的。(A simulink do with self-adaptive fuzzy PID system, through three fuzzy FIS: dkp, dki, dkd to control the Kp, Ki, Kd, in order to achieve automatic adjustment of PID parameters can be objective.)

通过均值聚类实现四类数据的分类，一直在用(means clustering )

Emplyment Payroll system Coded in C++ working

these codes implement out of band carrier de activation for OFDM. the number of subcarriers is flexible.

根据风阻公式计算风力发电机的升力阻力的小程序 不知道风阻公式的自己查询(lift and resistant power of wind turbine)

蒙特卡罗方法（Monte Carlo method）在通量计算中的应用(Monte Carlo method applied in the flux calculation)

matlab粒子群程序，里面的bug请检查 (swarm)

说明：  通信系统中，信号在传输过程中会叠加上噪声，我们在分析时通常就用高斯白噪声来分析。此程序用来产生高斯白噪声。(communications systems, signal transmission in the process will superimposed on the noise, our analysis is usually used to Gaussian white noise analysis. This procedure used to produce white Gaussian noise.)

此程序能够很好的实现调频调相调幅等多种调制方式和多进制的调制。(This process can achieve the frequency modulation and amplitude modulation and other multi-band modulation.)
