Study on Curve Fitting Based on Least Square Method

Abstract

In engineering applications and scientific experiments,curving fitting is an important method to make a summary or prediction for a system.Therefore,the error of curving fitting becomes extremely important.The most popular method in curving fitting is least square method,which is widely used because it is more accurate and practical.The article curve-fits the data of experiment by way of least square method,and concludes and summarizes the whole process of curving fitting,in which some main procedures are processed in matlab.
