用java编写的可以用来做普物实验的程序，实现了最小二乘法，比手动计算数据块很多-Written by java objects can be used to make general experimental procedures, the least squares method, data blocks than a lot of manual calculation

最小二乘法拟合的实现，用的是java语言-zui xiao er cheng

使用java实现最小二乘算法，实现曲线拟合，实现多项式拟合(Using java algorithm to achieve the least squares, curve fitting, polynomial fitting)
