Details:

in matlab I get:


>> version

ans =

7.5.0.338 (R2007b)

>> coefs = [zeros(3,2,2); ones(1,2,2)]

coefs(:,:,1) =

     0     0
     0     0
     0     0
     1     1


coefs(:,:,2) =

     0     0
     0     0
     0     0
     1     1

>> 



Octave used to be the same:


>> version
ans = 3.2.3
>> coefs = [zeros(3,2,2); ones(1,2,2)]
coefs =

ans(:,:,1) =

   0   0
   0   0
   0   0
   1   1

ans(:,:,2) =

   0   0
   0   0
   0   0
   1   1



with the development version though:


>> version
ans = 3.5.0+
>> coefs = [zeros(3,2,2); ones(1,2,2)]
coefs =

ans(:,:,1) =

   1.00000   1.00000
   0.00000   0.00000
   0.00000   0.00000
   0.00000   0.00000

ans(:,:,2) =

   1.00000   1.00000
   0.00000   0.00000
   0.00000   0.00000
   0.00000   0.00000
