iir3

3阶iir滤波器设计，不采用matlab自带的滤波子程序，完全自己编写程序，可以十分方便的转化为c语言。(3-order IIR filter design, do not use built-in filtering matlab Subroutine entirely their own programming, can be transformed into a convenient c language.)

一个Matlab写的关于图理论以及其在机器学习中应用的教学用GUI软件(Write a Matlab on graph theory and its application in machine learning in the teaching GUI software)

％ y=filter(sig,fmin,fmax) ％ 对信号进行理想滤波，可完成低通，带通 ％ sig为被滤波信号 ％ fmin为下限频率，当fmin为0时为低通滤波器，当fmin>0时，为带通滤波器 ％ fmax为上限频率，fmax>fmin ％ fs为信号的采样频率 ％ y为经过滤波后的信号 (％ Y = filter (sig, fmin, fmax)％ of the ideal signal filtering, to be completed by low-pass, band-pass filter％ sig for signal％ fmin is the minimum frequency, when fmin for 0:00 for the low-pass filter, when fmin > 0, for the bandpass filter％ fmax is the upper limit frequency, fmax> fmin％ fs for signal sampling frequency％ y for the filtered signal)

GUI系统进行小波变换，能够将图像进行适当的压缩。(Wavelet transform GUI system, an image can be appropriately compressed.)

说明：  自己写的基于matlab的WAV声音文件报警的仿真程序(Write their own based on the WAV sound files matlab simulation program alarm)
