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 .
