Octave compatibility for `&)`

Another Matlab / Octave difference has been identified and solved:

Matlab:

y = [1 3 5; 2 4 6]; y([1 3 5]) = []
y =
2 4 6

Octave:

y = [1 3 5; 2 4 6]; y([1 3 5]) = []
y =
2
4
6

The pattern seems to be: if ~isvector(y) Matlab reshapes as a row, whereas Octave reshapes as a column.

This is now solved by explicitly reshaping as a row in that case
