Follow-up Comment #1:

It's unclear from your description whether this is because '-v7' is the
default in Matlab.

What happens if you open the Preferences in Matlab and set the default
"MAT-File save format" to either v6 or v7.3? Are you still able to save a file
with '-v7' and then append a variable to it with '-append'?

According to Matlab's help for the save command, if the file is in v6 format,
you need to use both '-append' and '-v6'. If that's true, it doesn't seem that
unreasonable to require the same in Octave with '-v7'.

But it might be a useful enhancement if Octave were able to detect and use the
existing file format when saving with '-append'.
