hierarchical feature selection code in matlab..

高阶谱分析中的实现三阶累积量计算的源程序。(High-order spectral analysis of the calculation to achieve third-order cumulants of the source.)

matlab 二维圆柱绕流，使用波尔茨曼方法进行数值模拟(cylinder，about cylinder in lattice boltzmamn method)

在matlab编程环境下，实现一个跟windows自带近似的画图板程序。(In the matlab programming environment with windows built to achieve a similar drawing board procedures.)

this file is to solve the problem of the tridiagonal and banded systems

单泡声致发光的中气泡半径的计算及其分析。(Calculation and analysis of single bubble sonoluminescence bubble radius.)

信号处理，仿真模拟简单的信号传输，是一个简单的实例(It consists of a core program, which provides basic functions for mathematical computation and graphics, and various specific toolboxes providing specialised functions for various fields of engineering such as control systems and signal processing. We use Matlab for computer added learning for this project.)

　Kmeans 算法是聚类分析中使用最为广泛的算法之一，其每个类别均用该类中所有数据的平均值(或加权平均)来表示，这个平均值即被称作聚类中心。该方法虽然不能用于 类别属性的数据，但对于数值属性的数据，它能很好地体现聚类在几何和统计学上的意义。(Kmeans algorithm is the most widely used cluster analysis algorithm, each category with the average of all data in the class (or weighted average) to represent the average is known as the cluster center. Although this method can not be used The class attribute of the data, but data for numeric attributes, it can well reflect the significance of clustering on the geometry and statistics.)

OFDM-Chirp波形的自模糊函数和互模糊函数，文件夹里面带了计算自模糊函数和互模糊函数的MATLAB文件ambgfun.m，不必用解析法做。带的ambgfun.m复制于MATLAB2017B能计算自模糊函数和互模糊函数(Self-ambiguity function and cross-ambiguity function of OFDM-Chirp waveform, which is calculated by MATLAB file ambgfun.m rather than by analytic method.)
