Thanks for the feedback, Rik.

I thought something like this might be taking place. Maybe something to keep in mind if the relevant functions are one day refactored otherwise, as you say, very low priority.

The code is in libinterp/corefcn/pr-output.cc beginning at line 2032 (dev branch).

Unfortunately, the way Octave printing works is to show the initial name and equals sign (for example, "myvar =\n\n"), but after that the rest of the printing routines have no idea what the name of the variable being printed is. To fix this would require changing the function prototype for not just print_nd_array, but octave_print_internal which has many variations. I'm not sure it is worth that effort.

Confirmed. It would be better to use the variable name rather than "ans" for clarity.

When an array of more than two dimensions is displayed, 'ans' is used for the name of the variable:

This is a little bit misleading as there is no variable 'ans':

In comparison, Matlab displays the following:
