colleration in fingerprint

此程序为在MATLAB环境下编写的模糊控制模块，通过模糊判断改变ＰＩＤ控制的参数，实现模糊ＰＩＤ控制。(This program is written in the MATLAB environment, fuzzy control module to change the PID control parameters, the fuzzy PID control, fuzzy judgment.)

十字交叉阵的波束形成，crossarray beamform(crossarray beamform)

利用matlab软件产生高斯白噪声和有色噪声的程序及程序说明(Using matlab software to produce white gaussian noise and colored noise procedures and instructions)

涉及到简单的傅里叶变换程序说明了其原理以及基本的使用方法，适合入门者(Comes to simple Fourier transform procedure describes the principle and basic use, suitable for beginners)

1. 按照式计算相似性矩阵 2. 排除自身的相似度 3. 按照式计算归一化矩阵 4. 按照式计算归一化拉普拉斯图矩阵L 5. 计算L的特征向量，将前个特征值最大的向量按列放置成一个矩阵，即依次为前个特征值最大的特征向量 6. 归一化X形成矩阵Y 7. 对矩阵Y按每行为一个数据点，进行k-means聚类，第行所属的类就是原来所属的类。(1. similarity matrix based on formula computation 2. rule out your own similarity. 3. normalized matrix based on formula computation 4. normalized formula Laplasse matrix L according to formula. 5. Calculate the eigenvectors of L. Place the vectors with the largest eigenvalues in columns into a matrix, that is, the eigenvectors with the largest eigenvalues in turn. 6. normalized X formation matrix Y 7. K-means clustering is applied to matrix Y according to one data point per behavior. The first row belongs to the original class.)
