If (classic) MATLAB had scalars the answer would be "ans = 1", but
it has no concept of an entity with less than two dimensions. But it
reallly makes no difference because what I am calling a "scalar" is
isomorphic with 1x1 (and 1x1x1, 1x1x.......x1 etc). That was the whole
point of my posting. (In linear algebra, a matrices can be viewed formally
as vectors, which are additive groups over a "scalar" fields. Those scalars
can be any algebraic set with '+' and '*' operators with inverse defined
for both etc. :-)
