利用music算法对 DOA 进行估计，基于均匀线阵(estimation of DOA bymusic)

fast matrix multiplication

KPCA可以用作数据压缩与提取。是一个很好的函数，可直接调用(KPCACan be used for data compression and extraction. Is a good function, can be called directly)

michelson contrast function for quality assesment of image

基于matlab迭代学习控制的程序，结合simulink，用s函数编写(Matlab-based iterative learning control procedures, combined with simulink, written s function)

LBG算法，初始码本随机给出，然后根据对训练矢量的划分，计算形心，更新码本。原代码中含有去空胞腔的程序。(LBG algorithm, given a random initial codebook, and then based on the division of the training vector, computing the centroid, update this code. Contains the original code to empty cell process.)

用Viterbi algorithm筛选经过含白噪声的信息。equalizer为采用Viterbi algorithm，有效减少ISI(码间串扰)，detector为简单的检验器。对比两者的误码率。信息数量为10001bit(using Viterbi algorithm method selecting the data. compared with simple detector. data length are 10001bits. Viterbi algorithm can reduce the affect of ISI （intersymbol interference）)
