drawrectangle not a defined function?
显示 更早的评论
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.

No, a trial is a full version.
What does
which drawrectangle -all
return?

Oh, it's part of the image processing toolbox. Of course, if the toolbox is not part of your trial, you won't have access to the function.

A trial is a full version of the products included in the trial license and installed.
This particular function needs the Image Processing toolbox
However, I have to wonder whether
ax = axes(app.UIFigure);
is correct. axes() does not apply to uifigure objects: you need uiaxes():
ax = uiaxes(app.UIFigure);
axes() applied to a UIFigure would give you an error about undefined function isvalid for datatype double.

You can request that products be added to the trial.
