一个简单的在figure中用鼠标画直线的例子。最终是想在matlab环境下编一个用鼠标画贝塞尔曲线的程序，现在正在研究中。(A simple figure using the mouse in a straight line drawn examples. Ultimately would like to matlab environment made a Bezier curve with the mouse painting process, now being investigated.)

zxb:提取wav波得语音声学特征MFCC，以及用praat提取wav波的基频。(zxb: extract acoustic features of voice wav wave was MFCC, and extracted with praat wav wave fundamental frequency.)

智能控制理论中课程设计的一个实例，是bp-pid控制的一个针对非线性的matlab课程设计任务书和源代码。(Intelligent control theory in an example of curriculum design is a bp-pid control design for nonlinear matlab program mission statement and source code.)

说明：  matlab,gatool,intialize population binary encoding the population,including selection, mutation,crossover

实现信号的SVD 分解,对信号中的奇异性进行监测，对突变信号点也可以很好监测(to complete the SVD for signals，Singularity of signal monitoring, signal monitoring point can be very good for mutations)

DCT and PCA for face recognation

数据排队的仿真过程，反映了源速率和相关参数的关系(it s the simulation of queueing model which reflects the relationship between source rate and parameters. )

说明：  此代码通过模拟退火算法优化BP神经网络进行汇率预测(This code optimizes BP neural network to predict exchange rate by simulated annealing algorithm)

通过直接在matlab软件环境下，运行split.m程序，生成结果（图像）(By matlab software environment directly in the running split.m program to generate the results (images) )

利用Matlab实现语音信号的数字水印技术.利用语音获取设备获取需要传送的保密语音信号；选择用于传输保密语音信号的普通声音载体；对加入水印信息的文件进行各种滤波处理，然后再对其进行水印提取，观察其结果；(Digital watermarking technology using Matlab voice signals using voice capture device to obtain confidential voice signals to be transferred Select common vector for the transmission of confidential voice speech signal adding watermark information on a variety of filtering files, and then its watermark extraction, observe the results )
