how to use curve fitting without using curve fitting toolbox?

9 views (last 30 days)
I want to use curve fitting tool in the matlab script without opening the curve fitting toolbox.
I have a data (x,u) and i want to use fiiting in the matlab m.file. I used interplant with linear method as indicated in the following image.
how can i write the code in the M file to do the same done using cftool?

Note that there is a difference between opening cftool and "opening the curve fitting toolbox". cftool is just a particular app within the toolbox.
