短时傅里叶程序实例，为读者提供短时傅里叶变换的入门学习与程序编写范例(Short-time Fourier instance, short-time Fourier transform to provide readers with an introduction and programming examples)

identifacation systems

this is about the matlab coding of any servo motor. the code shows how to calculate transfer function and use siso(single input single output) tool.

计算一维时间序列的Renyi熵，可作为脑电信号的特征提取方法，从而对脑电的复杂度进行分析(The Renyi entropy of one dimensional time series can be calculated as a feature extraction method of EEG signal, which can be used to analyze the complexity of EEG.)

说明：  C4.5决策树分类算法，用于进行数据分类(Classification algorithm)

Genetic and matlab programming

两个简单程序，一个是在空域和频域分别实现了两个矩阵的卷积。另一个程序主要是为了查看几个模板的空域及频域响应形式，方便理解(Two simple procedures, one is in the spatial and frequency domain is realized for the convolution of two matrices. Another program is mainly to see the airspace of several templates and frequency domain response form, to facilitate understanding)
