基于粒子适应度的惯性权值函数自适应调节每个粒子的惯性权值，使得粒子速度更新更有层次，更新速度更均匀(Inertia weight particle fitness function based on adaptive inertia weight of each particle, so that the particle velocity update more layered, more uniform velocity update)

说明：  matlab教科书第十章程序实例，内涵45个程序，绝对实用，程序中都有中文注解(Chapter textbook example matlab program, meaning the 45 procedures, the absolute utility, the program has Chinese comments)

Matlab功率谱计算，其中包含了关于功率的几种算法(Matlab power spectrum calculation, which contains the power of several algorithms)

关于matlab的详细资料，电子书籍，有基础介绍，算法，实例，代码，对于matlab的学习和应用非常有帮助。(For more information on matlab, e-books, a basic introduction, algorithms, examples, code, and for the learning and application of matlab very helpful.)

This m-file applies uniform quantization on audio signal and produced the Mean Square Quantization Error

it descibes about various matlab code

计算图像PSNR，非常高效的源码，具有一定的参考价值。(Calculated image PSNR, very efficient source, with some reference value.)

IMAGE PROCESING FAST FOURIER TRANSFORM

利用函数MadHG生成规则LDPC码的校验矩阵H，其行重为6,列重为3,行数为列数一半(行数越大越好)，H中任意两列没有围长为4的圈，并得到H对应的生成矩阵G，可以保证mod(G*H ,2)=0。使用方法为:[H,G] = MadHG(m,n,x),x= 1(得到的G左半部分为单位阵) or 2(G右半部分为单位阵),(use function MadHG Generation rules LDPC check matrix H, re-6, series of three, out for a few half of the number (A bigger the better), H 2 arbitrary no girth of the four circles, H counterparts and with the formation of matrix G, we can be assured of mod (G* H, 2) = 0. To be used : [H, G] = MadHG (m, n, x), x = 1 (the G part of the Left Front units) or 2 (G right half of the units RUF),)
