说明：  通过模型决定系数完成支持向量机参数优化，并建立基于大数据的支持向量机模型实现回归拟合(The parameters of SVM are optimized by the coefficient determined by the model, and the regression fitting is realized by the support vector machine model based on big data)

说明：  这是LU分解法求线性方程组的资料，讲解了LU分解的原理及过程，非常实用(LU decomposition seeking linear equations to explain the principles and process of the LU decomposition, very practical)

fluent软件UDF，用于焊接过程模拟，是高斯分布的面热源。(weld heart source)

地震数据球面扩散振幅补偿程序，fortran源代码。(sphdiv for seismic explorer)

Compaq Visual Fortran Error Messages，对于利用CVF编程的programmer是本很好的对照手册。(Compaq Visual Fortran Error Messages, programming, programmer for the use of CVF is a very good control of the manual.)

说明：  对该模型参数辨识采用递推最小二乘法，即 RLS（ recurisive least square）， 它是一种能够对模型参数进行在线实时估计的辨识方法。(The recursive least square method is used to identify the parameters of the model, that is, rls (recurisive least square), which is an online real-time estimation method for the model parameters)

说明：  该算法用于matlab，主要用于马尔可夫算法(THIS IS For markov algorithms)

用于求解非线性代数方程的全部解的函数，提供给大家学习使用(solutions, available to everyone learning to use)

求两个多项式的最大公约式，多项式按照如下格式输入，如果输入 3 //次数 1 2 3 4 //系数 则表示 1+2x+3x^2+4x^3(For two of the largest convention-type polynomials, polynomial input in accordance with the following format, if you type 3// number 1 2 3 4// coefficient express 1+ 2x+ 3x ^ 2+ 4x ^ 3)

这个程序用来计算四阶累计量，程序中有详细说明(This procedure used to calculate the fourth-order cumulant, the program in detail)
