Details:

Matlab's version of rat() supports complex numbers.  Octave's should as well.

For reference, here is a sample result:


rat (complex (0.5, pi))

ans =

  3×18 char array

    '1 + 1/(-2)        '
    ' +i* ...          '
    '3 + 1/(7 + 1/(16))'


I would argue that it might be better to have the real part of the number on
one line and the complex part on the next, rather than splitting the value in
to three parts.
