主要是基于extreme learning machine的改进算法，结合了增量学习(It’s mainly based on the extreme learning machine improvement algorithm, unified the increase study )

粗糙集属性约简过程中的下近似及上近似域的matlab实现(Rough set attribute reduction under the approximation of the process and on the realization of similar domain matlab)

emd源程序。emd源程序。emd源程序。emd源程序。emd源程序。(display the emd functions)

利用频率采样设计法设计线性相位FIR低通滤波器，画出h（n）、幅频响应、相频响应(Design of frequency sampling design method using a linear phase FIR low-pass filter, draw h (n), frequency response, phase frequency response )

要用灰色模型预测2020年人口数，请赐教(In the gray prediction model to the population in 2020 ..)

Synchronized Phasor Measurements and Their Applications (example 1-4)

Pake变换的Simulink仿真实现，即abc坐标到αβ坐标再到dq坐标系。非matlab自带模块，便于理解原理。(Park transforms Simulink Simulation, namely abc coordinates to αβ coordinate then dq coordinate system. Non-matlab module comes with easy to understand the principle.)

三相桥双极性PWM控制Simulink仿真，另加一滤波器观看PWM经过低通滤波后的波形，适合电力电子初学者(Three-phase bridge bipolar PWM control Simulink simulation, plus a watch PWM filter through after the low-pass wave filter for power electronics for beginners)

sample code to show how to perform digital filtering using fast fourier transform

最近搞设计弄来的一些资料 大家一起参考 基于matlab伪随机序列产生(engage recently obtained some design information together reference Matlab-based pseudo-random sequence generation)
