On The Fitting Of A Curve

With the high development of computer science, scientific calculation is more and more important. The analysis numeric is the important object for research of scientific computation. The purpose of the research on method of computation is to accomplish correct calculation and make the error as little as possible and make the computation times as quick as possible. In this article, one does a thorough research on the method of fitting of a curve, and makes a thorough analysis and comparison on usual fitting of a curve in error and run time. As a result, one makes a conclusion that we should combine the concrete problems with the every elements of fitting of a curve to choose the best method. At the same time, one gives the relevant program realization by using MATLAB Language.
