[Octave-bug-tracker] [bug #53179] Wrong result with bsxfun (single complex argument)

[Rik]

Follow-up Comment #2, bug #53179 (project octave):

This is almost certainly a bug in bsxfun.cc.  The following is taken from
bsxfun.cc:


if (result_type == "double")
  {
    if (tmp(0).isreal ())
      {
        have_NDArray = true;
        result_NDArray = tmp(0).array_value ();
        result_NDArray.resize (dvc);
      }
    else
      {
        have_ComplexNDArray = true;
        result_ComplexNDArray =
          tmp(0).complex_array_value ();
        result_ComplexNDArray.resize (dvc);
      }
  }
else if (result_type == "single")
  {
    if (tmp(0).isreal ())
      {
        have_FloatNDArray = true;
        result_FloatNDArray
          = tmp(0).float_array_value ();
        result_FloatNDArray.resize (dvc);
      }
    else
      {
        have_ComplexNDArray = true;
        result_ComplexNDArray =
          tmp(0).complex_array_value ();
        result_ComplexNDArray.resize (dvc);
      }


Notice how when the result type is "single" and complex, a double complex
NDAarray is used.  This may be a relatively simple fix.
