Perhaps you could explain what those MATLAB commands do. Not everyone here is 
familiar with MATLAB. For the most part, an API like "profile on; profile off" 
is inappropriate for the "profile" Python module. It profiles the times each 
function call takes, not each line. Turning it on and off doesn't make much 
sense. The API described in the above link is better for what it does.

If you want to visualize the profile, you may want to try RunSnakeRun:

If you want line-by-line profiling, you may want to check out my package, 
line_profiler:

   http://pypi.python.org/pypi/line_profiler/

Again, we don't turn it on and off like you might do in MATLAB. Just follow the 
directions and give up trying to find a correspondence with the MATLAB commands.
