在快速傅里叶变换大的基础上以对信号进行短时分析，能画出三维瀑布图。(In the fast Fourier transform big on the basis of the signal is short analysis, can draw 3 d waterfall diagram )

说明：  在处理数据的时候我们经常要算各个区间的频数,但是在matlab中没有这样的命令.当数据比较大的时候自己数就比较麻烦,这里编了个小程序,(Handle data in a time when we often have to count the frequency of each interval, but there is no such matlab in command. When the data when the relatively large number of on its own is too much trouble here编了个small procedures,)

一个基于信息最大化的盲信号分离算法，详细的文章可以在网络上搜索。(One based on information maximization algorithm for blind signal separation, detailed article on the network search.)

在matlab环境下，利用ode命令求解常微分方程组的学习算例(In the matlab environment, the use of the command for solving ordinary differential equations ode to learn examples)

读取图像进行小波去噪后，获取图像的prewitt算子轮廓(After reading the image wavelet denoising, to obtain images of prewitt operator profile)

数字信号处理，离散时间系统的相位、结构与状态变量描述典型题，能更好的理解离散时间系统(Digital signal processing, discrete-time systems the phase, structure and state-variable description of a typical question, can a better understanding of discrete-time systems)

根据归一化后的原始数据曲线，进行导数变换等，然后运用自组织神经网络进行藻种识别(According to the normalized data,we use the Differential switch,and then identify the HABs using the SOM.)

输入x,y的值，并将它们的值互换后输出。(Enter the x, y values​ ​ , and their values ​ ​ are interchangeable output.)

说明：  cone low in matlab for count MATLAB program to calculate the size of the law of the conical tank A time of emptying the tank

说明：  老外的MIMO程序，实现不同收发天线数，不同调制方式下的误比特率测量，运行ui-start(foreigners MIMO procedures to achieve different transceiver antenna several different modulation under the bit error rate measurements, run ui- start)
