Are you asking about the output format of complex numbers? Like so:

  >> 2i
  ans =  0 + 2i
  >> 2j
  ans =  0 + 2i

If so, no the "i" is currently hardcoded in the interpreter.

This could be done with a local modification and rebuild of Octave, or a
custom function (e.g. my_disp) to display complex numbers how you


Would that be of enough interest to patch the interpreter and have an "USE I OR J FOR DISPLAY" flag?
