近红外光谱提取后，matlab环境下可对NIR光谱数据进行正交信号校正(After the near-infrared spectrum extraction matlab environment can NIR spectral data orthogonal signal correction)

abaqus中的动态分析方法,含有inp、for文件希望能给动态分析，提供点参考(Methods of dynamic analysis of abaqus, containing the inp, hope can give a dynamic analysis for file, provide a point of reference)

NUMERICAL OPTIMIZATION: This is steepest descent method with constant step length to find the minima of f(x, y) = xy exp(− 2x^2 − y^2 + 0.3y) Graphical represxentation in 5 ways of solution, simple and clear explained.

这是FCBF的matlab程序。FCBF是比较实用的特征选择和降维的方法。在这个文件里面，有个word文件详细说明了FCBF的使用方法。本站只有FCBF的java程序。(This is a matlab program of FCBF. FCBF is a more practical method of feature selection and dimensionality reduction. Within the file, a word file detailed deccribed the usage of FCBF. However, the home station only has a java program.)

说明：  该程序可以求得任意两个长度相同的离散信号的互相关系数以及自相关系数，并绘制其图像(The program can get the cross-correlation coefficient of any two discrete signals with the same length, and draw the image of the cross-correlation coefficient)
