Does it exist some Octave command to apply Sturm ?
If it is not, I need to implement it how i can divide 2 polynomials and
returns the residue to me.For instance:
I want divide the polynomial [1,0,0,-4,1] with [4,0,0,-4] and it must return
the polynomial residue [-3,0],

Hello Tobal,

Are you looking for deconv()

>> [b, r] = deconv ([1,0,0,-4,1], [4,0,0,-4])
b =
   0.25000   0.00000
r =
   0   0   0  -3   1

HTH, Kai
