Hi,

First I have one question, why not migrate to GitHub or other ?
It would be great to be able to use markdown language and preview the bug
before we submit it.

Here is the problem with the bitxor function :

On Matlab R2017a (9.2.0.556344) :
>> byteVector=0:255;
>> data=0:499;
>> whos byteVector data
  Name            Size             Bytes  Class     Attributes

  byteVector      1x256             2048  double
  data            1x500             4000  double

>> c=bitxor(byteVector,data);
Error using bitxor
Inputs must have the same size.

>> c=bitxor(byteVector',data); %Transposing the first vector
>> whos c
  Name        Size               Bytes  Class     Attributes

  c         256x500            1024000  double
On Octave 4.2.1 :
octave:1> byteVector=0:255;
octave:2> data=0:499;
octave:3> whos byteVector data
Variables in the current scope:

   Attr Name            Size                     Bytes  Class
   ==== ====            ====                     =====  =====
        byteVector      1x256                       24  double
        data            1x500                       24  double

Total is 756 elements using 48 bytes

octave:4> c=bitxor(byteVector,data);
error: bitxor: size of X and Y must match, or one operand must be a scalar
octave:4> c=bitxor(byteVector',data); %Transposing the first vector
error: bitxor: size of X and Y must match, or one operand must be a scalar
octave:4> whos c
octave:5>

Can you please have a look ?
