    Engineer here: mostly use i, but have seen j used plenty. First time I saw j used was by a maths professor.

      Interesting I never saw j from a maths person. Friends (from a decade ago!) in electronics eng dep said they use j because i was reserved for current. perhaps the latter depends on the department.
