Follow-up Comment #5, bug #61473 (project octave):

`isequal` checks if its two inputs are equal. `eq` (same as `==` operator)
checks each *element* of its inputs for equality.

So, `isequal([], [])` returns `true` because both inputs are "equal". `[] ==
[]` returns `[]` because there are no elements to check equality for. `[1 2 3]
== 1` returns `[true false false]` because of broadcasting rules. Similarly
`[] == 1` returns `[]` as an extension of the same "broadcasting" rules.

One is an element-wise operation, the other one is not.
