用matlab实现的分类算法，非常经典的，功能齐全(Using matlab realize the classification algorithm, a very classic, full-featured)

PSO优化BP的源程序,加上作者的注释.(BP PSO optimization of the source, together with the author' s comments.)

Image reconstruction based on wavelet transform. is very useful to people who want to learn about image reconstruction

基于matlab simulink 的 电网电压跌落仿真试验模型(A samulation model of VSG based on matlab simulink)

说明：  灰色预测方法的特点表现在：首先是它把离散数据视为连续变量在其变化过程中所取的离散值，从而可利用微分方程式处理数据；而不直接使用原始数据而是由它产生累加生成数，对生成数列使用微分方程模型。这样，可以抵消大部分随机误差，显示出规律性。(The characteristics of the grey prediction method are as follows: First, it regards the discrete data as the discrete value of the continuous variable in its change process, so that the differential equation can be used to process the data; instead of using the original data directly, it generates the cumulative generation. Number, using a differential equation model for generating a series. In this way, most of the random errors can be offset, showing regularity.)

This function constructs a bottleneck (or toassociative) neural network.

说明：  采用卡尔曼滤波器的PID控制。控制干扰信号与测量噪声信号幅值均为0.002的白噪声信号。采用滤波器是控制效果明显改善。 (Discrete Kalman filter for PID control)

说明：  利用matlab生成的随机数做蒲丰（buffon）投针问题．(Is Pu Feng using the matlab production s random number (buffon) to throw the needle question. )

本代码可以实现CIC的抽取滤波功能，性能很好(This code implements the CIC decimation function, performance is very good)
