record my problems and solutions in pplane rectify pplane8 on MATLAB R2016b I have already solve this problem You only need add 'Parents' in meload = uimenu('Parents',mefile,'label','Load a system ...',... 'callback','pplane8(''loadsyst'',''system'');',... 'pos',1); Repeatedly change all this type of errors and it works and when you use latest matlab here is the problem you may meet:
'numb','off' -> remove all of these Key/Value pairs. Sometimes they are wrapped around a line end. So search for 'numb' and remove the 'numb','off' pair from each occurrence. 'call' -> 'CallBack' 'number' -> 'NumberTile'
if notice -> if ishghandle(notice) if gstop -> if ishghandle(gstop) if dud.notice & dud.noticeflag -> if ishghandle(dud.notice) & ishghandle(dud.noticeflag)
and use the latest Phase Plane and Slope Field apps https://github.com/MathWorks-Teaching-Resources/Phase-Plane-and-Slope-Field
