用matlab对照片进行频域变换，并进行简要分析比较DCT、DFT、WH等方式重构的图像与原始图像之间的差别，并写出报告(use matlab to perform the frequence transform and use DCT/DFT/WH to rebuild the picture, analysis the difference and report)

FSK调制解调MATLAB源代码 高斯白噪声 调制 眼图 信噪比 (FSK modulation and demodulation MATLAB source code modulation Gaussian white noise signal eye diagram )

说明：  ROC曲线绘制程序！matlab版！搜索，无重复。(ROC curve drawing program! matlab version! English, no repeat.)

简单的求逆矩阵中单个元素的程序。 用于求解逆矩阵中的单个元素值，基于定义 使用伴随阵/行列式的值求解 只适用于小矩阵。维数太大行列式的值就计算不出来了(Simple inverse matrix of individual elements in the program. For solving the inverse matrix single element values, with the value of the array/determinant of solving only apply to a small matrix-based definition. Value dimension to calculate the determinant is not too out)

c programe to write the table of given number. for beginers in c.

说明：  这是用matlab语言编写的数据处理的小程序，很好用的(using Matlab is the language of small data processing procedures, with the good)

HUFFMAN TREE的编码源代码 实测可用 适合初学者使用(HUFFMAN TREE actual source code is available for beginners)

再用主成分分析方法进行信号噪声去除。文件中包含三个子函数：1.Normalize_InputData，规则化输入数据；2.PCA_Reduce_Dimension，实现数据降维处理；3.PCA_Filter_Noise，实现噪声去除(the principal component analysis method for signal noise removal. The file contains three sub-functions: 1.Normalize_InputData, regularized input data; 2.PCA_Reduce_Dimension, to achieve data dimension reduction processing; 3.PCA_Filter_Noise, to achieve noise removal)

一个基于matlab的多机器人仿真平台，多智能体仿真(A Robot Simulator)

随机子空间法用于模态参数识别 能够识别频率阻尼(Stochastic subspace method for modal parameter identification )
