The Mathematica Toolbox
A Mathematica Profiler
Volume 5, Issue 3
An execution profiler for Mathematica programs is presented.
For any specified set of functions, the profiler can record the number
of times the functions were called, the total amount of time spent in each,
and how that time was partitioned among the head, arguments and body. It
can also display a call tree that shows where each function was called
and by whom.
