Yes, it's a normal profile. I called this enegetical because we use it to see 
how the energy is localised in a laser beam (gaussian beam), but you're 
right, this term may be confusing.

I didn't know imlab, so I had a quick look: interesting. It seems they 
essentially write C functions then interface them with scilab. That's a 
solution.
I personnally prefer functions written in scilab when speed is not crucial: 
* no compilation: it just works immediately on any platform (linux/windows).
* maintaining is easier: I believe that people who use scilab aren't 
necessarily C programmers (and that's why they use scilab: no declarations, 
easy and powerful functions available, no compilation). So, more users should 
be able to read (and adapt for their own needs) your scilab code rather than 
your C code.
