If you don't load orthopoly where is the definition of the unit_step() function in Maxima? There is indeed one in
orthopoly and it appears to be the same as the one you get when you have no packages loaded. Does anyone know? Is it
possible that orthopoly is loaded when you call unit_step?

I will have to take a look at the other dirac function but I believe that it is only recognised by laplace. I didn't
know there were two unit_step's, I will look into that as well. Also, thanks for your support of my work.
