微粒群算法结合灰色系统理论进行预测的matlab代码，精确度较高(Particle Swarm Optimization of gray system theory to predict the matlab code, high precision)

MATLAB手册 介绍MATLAB所有的功能 是一本电子书 内容详尽 (MATLAB manual describes all of the MATLAB function is a detailed e-book)

基于MatLab和VC编写程序，实现点云数据的快速建模，三角网格的绘制。(MatLab, and VC-based programming to achieve fast data point cloud modeling, triangular mesh rendering.)

说明：  BCH 编解码的MATLAB 实现。BCH码是一类重要而有效的纠正多个随机错误的循环码，由于该码具有严格的代数结构，所以是到目前为止研究得最为详尽、应用最为广泛的一类码，已有多种译码算法。(BCH codec of MATLAB. BCH is a kind of important and effective redress the wrong number of random cyclic code, as the code strictly algebraic structure, it is so far the most detailed study in, the most widely used type of a code has a variety of decoding algorithm.)

说明：  Welch法功率谱密度 Psd自功率谱 是用改进的平均周期图法来求随机信号的自功率谱估计 采用信号重叠分段，加窗函数和fft算法等计算一个信号的自功率谱估计（PSD）

simulink仿真 采用PI控制 进行直流输电仿真

有偏卡尔曼滤波器实现，可以用来消除无线定位中的非视距误差(Biased Kalman Filters can be used to eliminate wireless location in NLOS error)

此为基于二代提升小波的阈值压缩算法源码，其中可以设置小波变换的分解层数，使用的小波名称，及各层阈值设置计算公式中的参数。并将低频系数转化为十六进制，方便在其上进一步压缩，如采用Huffman压缩等，程序思路清楚，附有完整的注释，可以使用多种小波，并且很好得体现了二代小波的思想，对于初学小波者帮助很大。(based on the second generation of this upgrade wavelet compression algorithm threshold source, which can set wavelet transform decomposition level, the use of wavelet name, threshold levels and set the formula for calculating the parameters. And low-frequency coefficients into hexadecimal facilitate its further compression, such as the Huffman compression. procedures ideas clearly, with the integrity of the Notes, you can use a variety of wavelet, and reflected very well in the second generation wavelet thinking, For beginners who wavelet of great help.)

说明：  标准遗传算法求解TSP。算法采用交叉、变异、赌转轮选择(Genetic Algorithm for TSP)
