this is helpful to get better result in stock market pridiction.

2D-LDA, used for classification.

说明：  灰色理论认为系统的行为现象尽管是朦胧的，数据是复杂的，但它毕竟是有序的，是有整体功能的。灰数的生成，就是从杂乱中寻找出规律。同时，灰色理论建立的是生成数据模型，不是原始数据模型，因此，灰色预测的数据是通过生成数据的gm(1,1)模型所得到的预测值的逆处理结果。 此程序用来作灰色预测。 (Gray theory that the behavior of the system even though the phenomenon is dim, the data are complex, but it is after all, is orderly, there is a whole function. Gray number generation, that is, from the clutter to find out the laws. At the same time, the gray theory is to generate data model, rather than the original data model, therefore, gray forecast data to generate data through the gm (1,1) model by the inverse of the predictive value of the results. This procedure is used for gray prediction.)

可以将matlab中的mat文件转换成txt文件，方便其他的应用程序调用。(Mat files can be converted into a txt file and facilitate the application calls.)

说明：  水准路线平差计算程序，程序里面含有详细的中文解释，通俗易懂，便于应用。(Line level adjustment calculation program, the program which contains a detailed explanation of the Chinese, user-friendly, easy to use. )

灰色关联度分析程序，在数学建模中经常会用到，已调试成功。(Grey Correlation Analysis program, often used mathematical modeling has been successful debugging.)

MATLAB常用函数参考,查找起来非常方便，是matlab必备工具书(MATLAB function reference commonly used, search is very convenient, is an indispensable tool for matlab book)

Custom tools for MATLAB supporting analysis and design of nonlinear control systems are introduced in this paper. The paper demonstrates their use to solve sample nonlinear control problems and presents some of the MATLAB algorithms involved
