Basically, there is no "normal" way. Octave always stores the internal
type directly, so a scalar is a scalar and is stored as a scalar, even
though it behaves as 1x1 matrix in virtually all contexts. 1x1
matrices are normally immediately converted to scalars.

You can write your own C++ DLD function to achieve this, if it's really needed.
