mdl.residuals is not working for some unknown reason.

I have attached the code here using the LaTex button, but it looks like a single unreadable line, so i am attaching a picture of it as well.

Thanks for taking the time to look at this,

Alex

Never mind.

Residuals needs to be capitalized.

在 MATLAB Online 中打开

Try this instead:

r = mdl.Residuals.Raw

MATLAB prefers that you use its exact names with respect to its structures and structure fields, and since MATLAB is case-sensitive, every detail is relevant.

Figured it couldn't hurt to ask.

Nice talking to you again and have a great 2019!

Thank you! You, too!

It might be best to use the Contact Us link at the upper right corner of this page, and ask MathWorks directly for help. First, they will know all the capabilities that fitlm has (at least some of which may be undocumented), and second because your request may be more than most of us here have the experise to reply to. As well, if fitlm can’t currently do what you want, your request will be considered a request for an enhancement to fitlm in future releases, or an interim upgrade to the current release.
