To my understanding, rectangle() is an older function which serves to draw rectangular or rounded rectangular graphical objects. The goal is to create an image element in a figure, just like line().

On the other hand, drawrectangle() allows the creation of objects of class Rectangle. The goal is to define a rectangular ROI, more like an object-oriented evolution of getrect() than what I'd call a "drawing" tool. drawrectangle() is also a much newer (R2018x, I think?) tool.

Hmmm, I'm a bit curious about this myself. I use rectangle all the time, but not drawrectangle. It just tried

>> doc drawrectangle

and got "no results". I'm guessing drawrectangle is not part of MATLAB, but is part of some other MathWorks product.

Yeah, drawrectangle is a relatively new addition to the imuitools portion of Image Processing Toolbox.
