Follow-up Comment #1:

Matlab's own documentation says


B = any(A,'all') tests over all elements of A. This syntax is valid for
MATLAB® versions R2018b and later.


This is a very, very new addition to Matlab and it is unsurprising that Octave
does not implement it yet.

I've changed this report to be a feature request for the development branch of
Octave.

In the mean time, this code is equivalent and will work in Octave or in Matlab
versions before 2018b


B = any (A(:))


This code idiom of turning an ND-array in to a column vector is very common
and I don't think it hurts code readability.
