I've been programming in App Designer and I want to have a ROI over some axes that would return its position. However, for some reason drawrectangle is undefined as a function. When I look up the documentation for it through matlab it cannot find the function either. A lot of answers on different posts say it might be the path but the MATLAB folder is still in my path. Please help.
ax = axes(app.UIFigure);
drawrectangle(ax); %Undefined function 'drawrectangle' for input arguments of type 'matlab.graphics.axis.Axes'.

It needs R2018b or later.
