Hello.
I used MapleSim to obtain system's equation by "Equation Extraction."
In the equation, there is a strange command displayed as "preopt" and I have no idea know what this command does.
This command appears in piecewise that contains roots.
I used helps (both Maple's help and the help on the website) and googles but still don't get any idea.
Can anyone tell me what "preopt" command is?
