Undefined function or variable 'images' error using "images.roi.Circle"

I do not get the error running the code as a script but get it when running the exact code in a function. I am using R2019a.

Are you using load without using an output variable?

I discovered the problem, it was that the output variable was named “images”. I did not notice that. Sorry and thank you.
