网上的最小二乘法（GLS，OLS）大多只是个演示例子，并不能直接拿来用。本人对最小二乘法进行了封装，只保留了一个对外的接口函数，并附有详尽的参数列表说明，只需将两个文件加入到VC的工程中，使用时只需 #include "les.h" 后就可调用最小二乘法函数了。非常方便，可是包含了我的劳动成果的哟！-Most of least squares line is just a demonstration example, and can not be directly used. I carried the package to the least squares method, leaving only one external interface functions, together with a detailed descr iption of the parameter list, simply add the two files to the VC of the project, use only# include " les.h " After the least squares method can call the function. Very convenient, but contains the results of my work yo!
