Details:

I think broadcasting should work like #12, but #10 gives error.

10>  eye(4) .- (1:4)'
error: operator -: nonconformant arguments (op1 is 4x4, op2 is 4x1)
11>  eye(4) .* (1:4)'
warning: product: automatic broadcasting operation applied
ans =

   1   0   0   0
   0   2   0   0
   0   0   3   0
   0   0   0   4


12>  eye(4) .- repmat((1:4)',1,4)
ans =

   0  -1  -1  -1
  -2  -1  -2  -2
  -3  -3  -2  -3
  -4  -4  -4  -3

13> version
ans = 3.6.1-rc0
