本压缩包中包括了几个常用的经典的数据挖掘算法，有k_means，CART，fuzzy_k_means，id3，SVM，很有实用性(The compressed package includes several commonly used classical data mining algorithms, there are k_means, CART, fuzzy_k_means, id3, SVM, is very practical)

说明：  该程序是在matlab中实现卡尔曼滤波的一个程序代码(The program is implemented in the matlab program code of a Kalman filter)

第10章 非线性方程组求解.zip。是从书中光盘里直接拷贝的代码，放在这里，与大家共享，共同交流，希望对大家有帮助。(Chapter 10 of the nonlinear equations)

独立成分分析算法降低原始数据噪声，部分实现了追踪测速迭代松弛算法，有信道编码，调制，信道估计等。( Independent component analysis algorithm reduces the raw data noise, Partially achieved tracking speed iterative relaxation algorithm, Channel coding, modulation, channel estimation.)

Loggabor Lung cancer detection Steps 1. First enter the patient ID 2. Enter patients mail ID 3. Select Input image cross sectional view of lungs • After selection the image histogram equalized, • Gabor filterd enhance the image • Dilated gradient mask • Cleared border image • Calculate area • Possible location of cancer is traced by green boundary 4. Result
