Details:

In Matlab first argument to axes function can be a container for the axes,
e.g. a figure handle, so that the axes is created in that figure (rather than
the current figure).

In octave this syntax result in an error. Example:

in Matlab r2018a:


>> hfig = figure;
>> hax = axes (hfig)

hax = 

  Axes with properties:

             XLim: [0.0000e+000 1.0000e+000]
             YLim: [0.0000e+000 1.0000e+000]
           XScale: 'linear'
           YScale: 'linear'
    GridLineStyle: '-'
         Position: [130.0000e-003 110.0000e-003 775.0000e-003 815.0000e-003]
            Units: 'normalized'

  Show all properties


in Octave:


>> hfig = figure;
>> hax = axes (hfig)
error: axes: H must be a scalar axes handle
error: called from
    axes at line 90 column 7
stopped in /usr/local/share/octave/4.4.0/m/plot/util/axes.m at line 90
90:       error ("axes: H must be a scalar axes handle");
