I would like to know how the identification toolbox determines the pw linear functions. How do the breakpoints relate to the pw functions?

在 MATLAB Online 中打开

Many MATLAB and Toolbox functions are written in MATLAB itself. For those, you typically open them in the Editor window with

edit functionname.m

and see what is going on "under the hood". However that is not the case all functions. Many are not written in MATLAB, and are not editable.

If you can edit an m-file, sometimes you can see some of the code, but the real heavy lifting is done by a call to a DLL inside that m-file, so you can only get so far. They'll do that (I think) either for performance (speed) reasons or to keep that part of the source code proprietary.

One afterthought: The documentation (including the headers of functions) often cites reference material for the algorithms being used. These can be handy for determining what MATLAB is doing.
