IIR滤波器设计
现有一个信号：x(n)=1+cos(π*n/4)+ cos(2*π*n/3)设计及各种数字滤波器以达下列目的：
低通滤波器，滤除cos(2*π*n/3) 的成分，即想保留的成分为1+cos(π*n/4)
高通滤波器，滤除1+cos(π*n/4) 的成分，即想保留的成分为cos(2*π*n/3)
带通滤波器，滤除1+cos(2*π*n/3) 的成分，即想保留的成分为cos(π*n/4)
带阻滤波器，滤除cos(π*n/4) 的成分，即想保留的成分为1+cos(2*π*n/3)
1. 用MATLAB命令butterord求除滤波器的阶数,用命令butter设计各滤波器；画出滤波器幅度和相频相应 取各滤波器的系统函数H(z)。
(an existing signal : x (n) = a cos (* n/4) cos (2** n/3) design and digital filter to achieve the following objectives : low-pass filter, filter cos (2** n/3) the ingredients that want to retain an element of a cos (* n/4) high-pass filter, a filter cos (* n/4) components, namely to retain the element of cos (2** n/3) band-pass filter , a filter cos (2** n/3) components, namely to retain the element of cos (* n/4) band stop filter, the filter cos (* n/4) components, namely to retain the ingredients for a cos ( 2** n/3) 1. MATLAB order butterord except for the band Filter, using the order of the filter design butter; paint Filter magnitude and phase frequency of the corresponding filter system function H (z).)

functional_programming
This set of files enables working more easily with functions of functions for concise and powerful code.
A few highlights of this way of working:
* Map multiple inputs to multiple functions and assign multiple outputs with a single line.
* Use conditionals (like "if"), loops, and recursion in anonymous functions.

ImageSOMQuantization
This package implements vectoriel quantization according Self Organizing Map paradigm
It allows to :
1. generate a codebook training images set
2. reconstruct a test image according to the generated codebook
3. ute the Peak Signal to Noise Ratio (PSNR) between the test image
and the image obtained after quantization
4. estimate execution time of this process
