Introduction to Matlab in English | 15 Data fitting app

This video introduces the data fitting app in Matlab. We demonstrate the difference between fitting in Matlab and in Microsoft Excel and show how easy it is to do fitting using Matlab even for non commonly used equations.

Hello, big thanks for the videos! Could you tell me how to determine the type of equation from a known set of experimental data in order to then adjust the data?

Hello Usually you will have some expectations to the relation between the two parameters based on your understanding of the system and the general governing equations. So, you try the possible relations and find the one that the data fits well with. If you do not have any expectations of the type of equation, you try different shapes (linear, polynomial, power, exponential, ... etc.) and find the one with best fit. Hope this answers you question!
