这些例子只要直接调入matlab就可以应用，简洁方便。适合初学者(meaningful)

this is about matlab and its applications.

用MATLAB编写的svm源程序，可以实现支持向量机，用于特征分类或提取(Using MATLAB svm prepared by the source, can achieve a support vector machine for classification or feature extraction-MATLAB)

说明：  对给定的数据，利用PCA求取数据中主分量(Given the data, using principal component in the PCA data to strike)

用不同插值方法对数据进行一维插值，通过结果不难看出，不同的插值方法导致不同的插值结果(One-dimensional interpolation data with different interpolation methods is not difficult to see through the results of different interpolation methods lead to different interpolation results)

分数阶傅里叶变换matlab的实现，可以看看的(Fractional Fourier transform matlab realization, you can see the)
