load carEcon
whos carData carTrain carTest
mdl = fitlm(carTrain);
econPred = predict(mdl,carTest);

Plot the results. I used it in MATLAB machine learning course, however when I am using evaluateFit in my own version, it is not working.

evaluateFit(carTest.FuelEcon,econPred,"Linear Model")

Well, you'll need to see about where that course is, then, because the function isn't in the standard MATLAB distribution nor any toolboxes.

There are examples using plot() and the fitlm model and you could produce the same plot sequentially from it...but not as conveniently as a prepackaged routine, granted.

Without a link to the training/course, just looking, don't know there's anything can do...

Thank you. I can give you the link of the course. If you go to the subsection linear models(ex.11) under section Regression methods, you will find it.
