Details:

the squareform function (in the octaveforge statistics package) shows
different behaviour in Matlab and Octave when using this function in the
'tovector' direction.

In octave (3.8.1 on linux, 3.8.0 on OSX):
>> squareform(1-eye(3),'tovector')
ans =

   1
   1
   1

In matlab (R2012b on linux, R2013a on OSX):

>> squareform(1-eye(3),'tovector')

ans =

     1     1     1

I expected the results to be the same for Matlab and Octave. 

I'm not sure to what extent this really is a bug in the sense that is shows
behaviour inconsistent with the documentation; neither Matlab's nor Octave's
help say explicitly that the output is a row vector. The example given in the
Matlab help does however show that the output in Matlab is a row vector.
