The Profile() command collects profiling data for all currently named procedures and all procedures read from a repository for Maple procedures.

The Profile(proc1, proc2, ...) command collects profiling data for all specified procedures.

The Profile([proc1, tab1], [proc2, tab2], ...) command has a length two list , whose first element is a procedure and second element is an rtable . Profiling is enabled for each procedure with the profiling data specified in the rtable as its initial value. The rtable should be obtained by a call to GetProfileTable on the procedure.

The procedures that are already profiled are not modified by a call to Profile.

To stop profiling, use the UnProfile function.

a := proc(x)
if (x > 1) then
return 1;
else
return 0;
end if;
