[Octave-bug-tracker] [bug #45820] linspace() incompatibility with Matlab when N < 2

[Rik]

Follow-up Comment #7, bug #45820 (project octave):

Octave gets the single/double distinction correct.  Here is a part of the code
in data.cc for Flinspace


octave_value arg_1 = args(0);
octave_value arg_2 = args(1);

if (arg_1.is_single_type () || arg_2.is_single_type ())
  {
    if (arg_1.is_complex_type () || arg_2.is_complex_type ())
      retval = do_linspace<FloatComplexMatrix> (arg_1, arg_2, npoints);
    else
      retval = do_linspace<FloatMatrix> (arg_1, arg_2, npoints);

  }
else
  {
    if (arg_1.is_complex_type () || arg_2.is_complex_type ())
      retval = do_linspace<ComplexMatrix> (arg_1, arg_2, npoints);
    else
      retval = do_linspace<Matrix> (arg_1, arg_2, npoints);
  }


What does Matlab return for this?


x = [1:5]';
linspace (x, 10, 0)


It should be empty, but I wonder if the dimensions are 5x0?  Although, I'm not
certain that we need to copy them exactly in that regard.
