Chapter-2-basic-matlab

说明：  LDPC编码方法，解码程序，适用于1008长度的码字(LDPC coding and decoding process for codeword length 1008)

改进支持向量机在电信客户流失预测的应用论文(support vector machine for client discard)

本程序可以用于解决简单的matlab 整数规划(Simple integer programming matlab)

说明：  这是一个AWGN信道下，编译码仿真的C程序。本人已经用它产生数据绘制折线图！包含编码，译码，信道模拟，误码率计算 …… ,程序结构清晰，不复杂，适合与初学者来了解，基本通信流程！(This is an AWGN channel, the decoding simulation C program. I' ve used it to generate data to draw a line chart! Including encoding, decoding, channel simulation, bit error rate ... ..., the program structure clear, not complicated, for with the beginners to understand, the basic communication process!)

Incremental Principal Component Analysis

ifft和fft实现线性卷积,并与matlab中默认内置的conv()函数的结果对照，验证其正确性。(using ifft and fft to accomplish linear conviction. Comparing this method with matlab default function conv().)

其主要特点是直接对结构对象进行操作，不存在求导和函数连续性的限定；具有内在的隐并行性和更好的全局寻优能力；采用概率化的寻优方法，能自动获取和指导优化的搜索空间，自适应地调整搜索方向，不需要确定的规则。( Its main feature carries on the operation directly to the structure object, does not have the derivation and the function continuous definition Has the intrinsic hidden parallelism and better overall situation optimization ability Uses the randomization the optimization method, can gain the search space which automatically and the instruction optimizes, adjusts the search direction auto-adapted, does not need to determine rule. )

matlab中值滤波，滤去高斯噪声白噪声等相关噪声信号(matlab median filtering, filtered Gaussian noise, white noise and noise signal)

主要是用于仿真有限长螺线管内部的磁场分布(Is mainly used for the simulation of finite length solenoid magnetic field distribution inside)
