Tuning & Debugging

Mathematica's highly optimized architecture makes it easy to create programs that are both elegant and efficient. Its symbolic character lets you immediately run and test even the smallest program fragments. And it provides full-scale software engineering support, from arbitrarily detailed compilation control to novel high-level symbolic analysis.


Monitor dynamically monitor values during a computation

StepMonitor, EvaluationMonitor monitor built-in algorithms

Sow, Reap accumulate lists of values from within a computation

Print print any expression or graphic

PrintTemporary print temporary output, cleaning up at the end of a computation

Dialog enter a subsession at any stage in a computation

Evaluation ► Debugger start interactive debugger

Assert give an assertion to be checked when code is executed
