matlab扩展编程，系统的介绍了matlab扩展编程的用法和注意细节，对matlab的继续学习打下坚实的基础。(matlab extension programming, the system introduces the use of matlab extension programming and attention to detail, to the matlab' s continue to learn to lay a solid foundation.)

fisher线性判别器，方法简单直观，对于多维样本有较好的分类能力(fisherclassifer)

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)

this code is help you to draw Fourier Series . with this code you can change some variable and explain what change for education.
