tracer4m traces calls to methods and functions.
Object-oriented design is about distributing responsibilities among interacting objects.
The objects should be small and focused. This results in a complex flow of calls.
Furthermore, in a GUI the user manipulates controls, which in turns trigger events and
chains of calls to methods and functions. There is a need to trace the calls.
The goal of tracer4m is to support unit testing, debugging, and analysis of existing code.
Example based on "Example - Using Events to Update Graphs" from the Matlab on-line help

feobject = fcneval( @(x,y) x.*exp(-x.^2-y.^2), [-2 2 ] );
fcnview.createViews( feobject );
log = TraceHistory.Instance;
log.setup( { 'fcneval', 'fcnview', 'createViews' } )
feobject.FofXY = @(x,y) x.*exp(-x.^.5-y.^.5);
disp( log )
%
log.clearHistory
feobject.Lm = [-8 3];
disp( log )

Part of the result is depicted in the image above.

Documentation: tracer4m_demo.html, which is generated by PUBLISH, discusses and demonstrate the use and behaviour of tracer4m.

I would appreciate comments especially regarding requirements on tracing tools for Matlab

Version Published Release Notes
1.1.0.0

Previous upload failed. Better luck this time :-)
Fixed the problem with R2016a reported by Therry. The revised code is tested only on R2016a, but "should" run on older versions.

Removed the limitation regarding function name reported by Jesse Hopkins. Now it also takes file names with wildcards.
