As an EE, I never had problems switching between i and j, and none of my
college friends seem to have had problems either. Perhaps because
everyone was taking EE classes at the same time as math classes, so i
and j were always in use at the same time. The only time it was
confusing if someone wanted to use i or j as an summation index. (Which
I always felt was a bad idea because j looks very much like i which
looks like 1 at the small font sizes used for summation indices.)
Besides, I don't hear much complaint from mathematicians that maxima
uses %i instead of just i. :-)
