matlab的解密程序，目前不支持MultiSelect，对文件进行解密(MATLAB decryption program, does not support the MultiSelect to decrypt the file)

this is 3d tr model for airplane target tracking

The first scheme is based on the spatial locality of feature vectors corresponding to similar images. Learning is effected by modifying the query vector to incorporate the positive examples. The second scheme is based on “distorting” our view of the feature space. An new similarity distance between an image and the query is learned from the relevance feedback.

利用遗传算法实现无功优化，寻找最优点进行无功补偿(Reactive power optimization based on genetic algorithm)

说明：  Lstm进行时间序列预测，预测股票数据，按日的数据(Prediction of time series by LSTM)

用有限差分法来解偏微分方程，采用高斯——赛德尔迭代方法，并用前后两次迭代差的矩阵的无穷范数作为是否停止迭代的依据。(Using finite difference method to solve partial differential equations, using Gauss- Seidel iterative methods, and poor before and after the two iterations of the infinite matrix norm as the basis of whether or not to stop iteration.)
