Help with ismatrix compatibility testing

Octave has had the ismatrix() command since 2002, but Matlab added one in
2010 and it doesn't appear that the two are exactly the same.

Could someone with a recent edition of Matlab (>2010) run the following and
report the results.

It might be easiest to use "diary on", run the commands, and then "diary
off" and upload the file since there are quite a few tests.

Commands to run:

ismatrix ({1,2;3,4})
[x(1:2,1:2).a] = deal (1,1,1,1);
ismatrix (x)
ismatrix ([])
ismatrix (zeros (10, 0))
ismatrix (zeros (0,10))
x = zeros (0,10,0,0,0)
size (x)
ndims (x)
ismatrix (x)
x = zeros (0,10,0,1,0)
ismatrix (x)
isscalar ({1})
isvector ([])
isvector (1)
isvector (zeros (1,0))
isvector (cell (1,3))

Thanks,
