polyfit

matlab数据分析的经典算法，可以用于数据分析(matlab data analysis of the classic algorithms, can be used for data analysis)

包含Jacobi和Seidel两种迭代法，用于求解线性方程，计算简单，收敛快(Contains two kinds of Jacobi and Seidel iterative method for solving linear equations, computing simple, fast convergence)

说明：  在matlab2019B中，已经将princomp函数改为了pca函数，功能相同，函数名改变，所以如果要使用，记得将老版本的代码中的princomp改为pca。(In MATLAB 2019b, the principal function has been changed to PCA function. The functions are the same, and the function name changes. So if you want to use it, remember to change the principal function in the old version of the code to PCA.)

wavelab预编译文件，能加速wavelab的运行，给那些matlab不能编译m文件的用户准备的。(wavelab pre-compiled documents can be accelerated wavelab of operation, Matlab not to those documents compiled m users of.)
