SVM的多分类问题MATLAB工具包。传统的SVM只支持二分类问题，MATLAB自带的工具包也存在同样的问题。可以在setpath中导入此包，便可轻松将SVM问题扩展到多分类的层面。(A matlab toolkit to solving multi-classification problems based on svm. Traditional svm and the matlab toolkit svmtrain can only support for bi-classification problems which could hardly satisfy users requirments. U can import this toolkit by click setpath and can easily do what you like.)

本章介绍了该水平直线阵朝向校准方法的意义和背景，研究了水平直线阵朝向校准方法的原理，分析了朝向模糊问题并介绍了消除模糊的方法。提出了校准过程中可能出现的真实朝向计算公式发生改变的问题，并针对性地给出了信源船位置的选择原则，即远场原则，尽量法向入射原则和同侧入射原则。进行了计算机仿真，初步验证了这一朝向校准方法的可行性。分析了改变信源角校准阵朝向的次数对阵朝向校准精度的影响，次数越多，朝向校准精度越高。但增大校准次数会增大成本延长时间，实际操作中，在满足校准精度的前提下，尽量减少校准次数。验证了此法满足预期的朝向校准精度指标。

低通抽样定理程序有课程设计的要用的自己看看吧(Low-pass sampling theorem of the curriculum design process should take a look at your own)

实现高通和低通滤波，主要是先进行傅里叶变换，然后对频谱图滤波后再逆变换得到滤波之后的图片(High-pass and low pass filter, mainly the first Fourier transform, frequency spectrum and then inverse transform filter and filtered image)

VC实现对MATLAB的调用，对于研究二者混合编程的人比较有用(VC++ implementation of the MATLAB call for the mixture of the two studies were more useful for programming)
