计算两个离散变量x和y的联合熵z = H（x，y）。 输入：x，y：两个相同长度的整数向量输出：z：联合熵 可以使用，有利于学习目的(Compute joint entropy z=H(x,y) of two discrete variables x and y. Input: of x, y: two integer vector of the same length Output: z: joint entropy good for learning purposes)

计算指纹方向场的代码。。。。。。。。。。。。(code for computing orientation of fingerprint )

对一维信号的过采样函数，采用SINC插值的方法，可以使输出信号更加平滑。函数用法有说明，并附有简单程序进行验证说明。希望对有需要朋友有用! 有问题欢迎留言交流！(For the oversampling function of one-dimensional signal, SINC interpolation method is used. The usage of the function is explained, and a simple program is attached to verify the explanation.)
