To "subtract" two matrices with different dimensions in Octave (Matlab)

With the current version (3.6) of Octave, simply subtracting will work

> a = [1 2; 3 4; 5 6; 7 8]
> b = [1 -1]
> a - b
ans =

   0   3
   2   5
   4   7
   6   9

Edit: Apparently this will also work in Matlab starting with the upcoming release (2016b).
