Signal library problem

[JORGE JONATHAN DIAZ PIÑA]

hi!

i'm using your library in Octave and i have a problem in the function ss2tf, the value returned of the function should be a vectors and the size of this depend of the grade of the matrix, but the function returns a vectors who depend of te numbers diferents of zero.

if you don't understand me i put a example:

--this is mat:

A=[1 1 0; 1 -1 0; 0 0 -2];

B=[2; 1; 1];

C=[1 0 1];

D=[0];

---Using matlab the result is this:

>> [ num , den ] = ss2tf( A, B, C, D )

num =

     0     1     2     0

den =

     1     1    -2     0

---Using octave the result is:

[ num , den ] = ss2tf( A, B, C, D )

num =  1

den =

   1  -1

---------------

octave don't return the correct result and send a diferent size
