问题描述
Each row is a sample containing two numbers x and y, where x is the input feature and y is its corresponding response. Notice that, x and y are splited by ‘\t’.
For example, x is 0.025817872 and y is 1.072778871 in
0.025817872 1.072778871
给定一个文件data,有x,y两组数据,进行多项式拟合。很简单的一个问题,基本是学习python的numpy库一些函数的使用和plt的画图。
