Scientific notation problem

[Yunfei Ding]

If I have a matrix: 

A=[0,1e3,0;1e-9,0,0]

Octave gives:
A =

  0.0000e+000  1.0000e+003  0.0000e+000
  1.0000e-009  0.0000e+000  0.0000e+000

However if I have a matrix:

A=[0,1e0,0;1e-9,0,0]

Octave gives:

A =

   0.00000   1.00000   0.00000
   0.00000   0.00000   0.00000

So I lose the data 1e-9 in the second row. It seems like Octave decides what to do according to the first row of the data. How can I force it to use scientific notation all the time?

Thanks a lot!
