Root PropertiesLanguagestringSystem environment setting.ParenthandleHandle of parent object. This property always contains the empty matrix, asthe root object has no parent.PointerLocation[x,y]Current location of pointer. A vector containing the x- and y-coordinates of thepointer position, measured from the lower-left corner of the screen. You canmove the pointer by changing the values of this property. The Units propertydetermines the units of this measurement.This property always contains the instantaneous pointer location, even if thepointer is not in a MATLAB window. A callback routine querying thePointerLocation can get a different value than the location of the pointer whenthe callback was triggered. This difference results from delays in callbackexecution caused by competition for system resources.PointerWindow handle (read only)Handle of window containing the pointer. MATLAB sets this property to thehandle of the figure window containing the pointer. If the pointer is not in aMATLAB window, the value of this property is 0. A callback routine queryingthe PointerWindow can get the wrong window handle if you move the pointer toanother window before the callback executes. This error results from delays incallback execution caused by competition for system resources.Profileon | {off}M-file profiler on or off. Setting this property to on activates the profiler whenyou execute the M-files named in ProfileFile. The profiler determines whatpercentage of time MATLAB spends executing each line of the M-file. See alsothe profile command.ProfileFile M-file nameM-file to profile. Set this property to the full path name of the M-file to profile.ProfileCount vectorProfiler output. This property is a n-by-1 vector, where n is the number of linesof code in the profiled M-file. Each element in this vector represents thenumber of times the profiler found MATLAB executing a particular line of2-419
