BUILT-IN WOLFRAM LANGUAGE SYMBOL
is an option for Trace and related functions which specifies the maximum nesting of evaluation chains that are to be included.
- Setting TraceDepth->n keeps only parts down to level n in nested lists generated by Trace.
- By setting TraceDepth, you can make Trace and related functions skip over "inner" parts of a computation, making their operation more efficient.
A recursive definition for finding Fibonacci numbers:
Trace only evaluations through depth 3:
Trace all evaluations:
