fast and simple voxel traversal algorithm

将多个变量通过线性变换以选出较少个数重要变量,是一种多元统计分析方法。(Analysis of the relationship between several variables and a special variable )

噪声信号产生软件，非常不错的，大家可以下载试试，一个简单产生白噪声的软件(Noise signal generator software, very good, we can try to download a simple software generates white noise)

说明：  卡尔曼滤波原理及应用代码程序，中国工信出版社(Kalman Filter Principle and Application Code Program,China Industrial and Information Press)

说明：  高等光学仿真-光波导、激光书中的部分程序代码(Higher optical simulation- optical waveguide laser book code)

这是有关matlab 学习的一些技巧和程序代码的编写，其中有SIMULINK和matlab程序两部分(matlab study)

函数调用求解三维空间中的最优解 采用惯性权重递变的粒子群算法(use PSO serve the normal problem by transmutation of inertia weight )

用于坐标转换 空间球形极坐标转化为空间直角三维坐标(For spherical polar coordinates space coordinate conversion into rectangular space three-dimensional coordinate)

在matlab环境下,产生（-1，+1）均匀分布的均值白噪声的程序代码(Matlab environment, generate uniformly distributed white noise code (-1,+1))

经典的二阶矩四阶矩信噪比估计，有不经过上采样、成型滤波和经过上采样、成型滤波的两种版本。加噪方式也分别用了matlab自带函数和自写两种版本。望大家参考。(Second Moment classic SNR estimation fourth moment, there is not through the sampling, the shaping filter and sampled, two versions of shaping filter. Plus noise mode were also comes with a matlab function and self-written versions. Hope you reference.)
