Random process function codes for communication engineering students to understand the concept of statistical analysis.

这是一个用matlab写的关于数独的程序，对于喜爱数独的伙伴会很有帮助，程序已经测试过，没有问题，而且有注释。(This is for soduk,it will be helpful for people who like it.)

该程序是VCO的simulink不同实现。设置不同的参数可得到不同的仿真效果。(that the procedure was different VCO Simulink achieve. Set up different parameters can be obtained simulation results.)

fft离散傅立叶变化，广泛应用数字信号处理中。(Discrete Fourier fft change, the wider use of digital signal processing.)

滑模变结构控制matlab仿真一书中第9章程序的修改版(Sliding mode variable structure control simulation matlab book Chapter 9 of the modified version of procedure)

此为模式识别中Parzen窗法估计概率密度函数。 全部程序流程如下： 1、读取FAMALE.TXT文件把身高或体重给数组，并求x1的样本数N1和窗宽、体宽； 2、读取MALE.TXT文件把身高或体重给数组，并求x2的样本数N2和窗宽、体宽； 3、读取Test2.txt文件把对应的身高或体重给数组A并求A的样本数M； 4、利用Parzen窗法估计概率密度函数判别男女性别； 5、对本判别的错误率进行统计。 (This is the pattern recognition Parzen window method to estimate the probability density function . All program flow is as follows : 1 , read FAMALE.TXT file to height or weight to the array, and find the number of samples x1 N1 and window width , body width 2 , read MALE.TXT file to height or weight to the array, and find the number of samples x2 N2 and window width , body width 3 , read Test2.txt file to the corresponding height or weight requirements for the array A and A is the number of samples M 4 , the use of Parzen window method to estimate the probability density function of gender discrimination 5 , determine the error rate of the statistics . )

Transform two case , the one case 1 is Fourier the 8X8 size and then use the mask to clear the high fitter . the second case 2 is cosine the 8X8 size and then use the mask to clear the high fitter .
