Outputs the function profiling results to the console
a Scilab function
showprofile on a function, the profiling of this function must have been first activated:
either by using the add_profiling command.
Once the function has been executed, calling
showprofile outputs to the console the profiling results.
For each function line (including the header of function), are printed the following informations, in order:
the total number of times the line was called
the total CPU time spent in the line (in seconds)
a measurement of the interpretor effort to interpret the line
the number and source code of the line
An example of output:
|1 |0 |0| 1: function x=fun(n) |1 |0 |0| 2: if n > 0 then |1 |0 |2| 3: x = 0; |200|0.01|0| 4: for k = 1:n |200|3.99|5| 5: s = svd(rand(n, n)); |...|... |.| ...
Here we can see that the 5th line of the function has been called 200 times, for a total CPU time of 3.99 seconds (and an effort of 5 to interpret the line).
Note: due to the precision limit of CPU time measure (typically one micro second), some executed lines which execution is very fast may appear with a CPU total time of 0.
// Function to be profiled function x=foo(n) if n > 0 then x = 0; for k = 1:n s = svd(rand(n, n)); x = x + s(1); end else x = ; end endfunction // Enables the profiling of the function add_profiling("foo"); // Executes the function foo(200); // Prints the function profiling results to console showprofile(foo)
