Abstract

Analyzing discrete data in the real world and applying the results of that analysis is something that people do all the time. It has a long history, and it involves different fields. To be able to better analyze the data, people often use various methods. Each of these approaches has its own history, as well as its own advantages and disadvantages. There are similarities between them, but there are also many differences. Among them, interpolation and fitting are both important methods for processing discrete data. They have similarities, but they are different in theory and practical application. To better understand and learn interpolation and fitting, this paper will compare interpolation and fitting. The author will use the method of contrast to briefly introduce interpolation and fitting, and then explain the differences between interpolation and fitting in terms of theory and practical application. In this paper, the author first introduces the definition of interpolation and fitting respectively, and briefly introduces the interpolation and fitting of several different methods. Then, the definition of interpolation and fitting is compared, the characteristics, advantages and disadvantages of the two are described, and the application of interpolation and fitting is compared from finance, meteorology, engineering and other fields.
