Null-space---MATLAB

useful code in matlab add document

字符识别，MATLAB程序的。可以运行。基于神经网络(Character recognition)

preisach模型磁滞回线，不同N可以调整模型精度。(preisach hysteresis loop model, you can adjust the different N model accuracy.)

adaboost 测试，te_func_handle is a handle to the testing function of a learning (weak) algorithm whose prototype is shown below.(te_func_handle is a handle to the testing function of a learning (weak) algorithm whose prototype is shown below.)

说明：  用MATLAB m文件编些的DS-CDMA 仿真程序

ISODATA法分类IRIS数据集，压缩包中包括两个.m文件，运行provaisodata_4D.m可直接分类。或者通过isodata_4D.m设置参数也可以得到结果。程序有详细注释，很容易懂。最后结果既有文字描述，也有图形输出。(ISODATA classification method IRIS data set, compressed package includes two. M files, run provaisodata_4D.m direct classification. Or set the parameters by isodata_4D.m can get results. Procedures detailed notes, it is easy to understand. Final results of both the written description, there are graphical output.)

MATLAB仿真二阶锁相环PLL，希望对大家有用(Second-order phase-locked loop)

有详细的注释，AHP层次分析法计算判断矩阵的最大特征值,多元数据分析的主分量分析投影。( There are detailed notes, Calculate the maximum eigenvalue judgment matrix of AHP, Principal component analysis of multivariate data analysis projection.)

matlab最大特征值计算，很简单，对矩阵中数据替换就可以。(matlab largest eigenvalue calculation is very simple replacement of the data matrix can.)

说明：  这个是利用图像分解和Logistics混沌序列可以对图像先进行加密然后进行隐藏在另一个图像中再进行解密(This is the use of image decomposition and Logistics chaotic sequence can be encrypted on the image first and then proceed to hide in another image and then decrypt)
