空间信道模型，特别适用于MIMO。有多种场景可以选择，并可根据需要调整参数(SCM)

一种用于非线性降维的流形学习算法，主要是先考虑用每一点处的局部切空间表示该点处的几何特征，然后都局部切空间进行排列(A manifold learning algorithm for nonlinear dimension reduction, mainly consider to use every bit of the local tangent space representation of geometric feature at that point, then the local tangent space alignment )

在非正交（NOMA）环境下，固定功率分配和树形算法分配的比较，说明树形的优势(In the non-orthogonal (NOMA) environment, relatively fixed power allocation and distribution tree algorithm, explain the benefits of tree)

小波包分析提取振动信号中的特征频率，有较好的参考价值，借鉴了主成分分析算法（PCA）。( Wavelet packet analysis to extract vibration signal characteristic frequency, There are good reference value, It draws on principal component analysis algorithm (PCA).)

说明：  matlab的程序cnn编写，对图片进行分类并预测，最后完成搜索功能， 输入图片路径给出所有同类的图片结果(matlab program cnn train and predict search function and so on)

说明：  喷管中气体流动现象及参数测定。基于MATLAB编写 (Nozzle in the gas flow phenomena and parameters measured. Prepared based on the MATLAB)

说明：  现代谱估计的源程序，包括直接法，间接法和窗函数法(Modern Spectral Estimation of source, including direct, indirect method and the window function method)
