Even for the built-in functions listed in Matlab docs for bsxfun? Are
you thinking of cases where a complex value can be generated from real
arguments, for example? At least in those cases, I think it doesn't
matter for Matlab because a complex variable is just a double value
with a complex part. But it does matter for Octave since real and
complex are separate types.
