Bases for all 4 fundamental subspaces

主要是利用MATLAB来实现系统的聚类分析，其中包括代码和功能说明。(Is to use MATLAB to implement the system of cluster analysis, including code and functional specifications.)

MATLAB的所有函数集合，很详细，可以节约不少时间的(MATLAB function of all a collection of very detailed, you can save a lot of time)

利用DCT域进行扩频水印的嵌入,含实验图像，和各种经典的攻击方式。可选择嵌入强度和攻击强度。利用Matlab编写(DCT domain using spread-spectrum watermark embedding, with the experimental images, and various classical attacks. The option embedded in the strength and intensity of attacks. Prepared using Matlab)

This implementation of progressbar is intended to be extremely simple to use while providing a high quality user experience. Features: - Can add progressbar to existing m-files with a single line of code. - Supports multiple bars in one figure to show progress of nested loops. - Optional labels on bars.

说明：  OFDM系统接收部分的matlab仿真源代码(OFDM system receives some source code matlab simulation)

matlab编写的预应力混凝土梁全过程分析，并给出最后的弯矩曲率图。(prestressed concrete beam matlab prepared the whole process of analysis, given the last moment curvature diagram.)

巴特沃斯滤波器，切比雪夫滤波器，椭圆滤波器设计及比较，同样的设计参数指标，在同一张图中比较三种滤波器的幅频响应波形，并用统计图画出各滤波器所需阶数。(Butterworth filter, Chebyshev filter, elliptic filter design, the same design parameter index, with a figure in the comparison of three filter frequency response waveform, and use statistical picture of the desired order of each filter.)

数字通信原理基于matlab仿真计算，采用matlab语言仿真通信原理基础内容：包括随机信号、调制解调、信源信道编码和滤波器等相关通信系统的仿真实现，建议具有matlab使用能力的人使用，对于加深自己对通信原理理论知识的理解很有帮助(Digital Communications Principles Matlab-Based Simulation Approach)

一个横好的谱估计算法，AM ma 和arma模型，可以自动的选取。(A good cross-spectral estimation algorithm, AM ma and arma model selection automatically.)
