Hello, this is Hao Lai.

I am using octave 1.1.1 for linux.

Octave produces the following result when I
try to do a partial fraction expansion.

octave:2>   b = [1,  1, 1];
octave:3>   a = [1, -5, 8, -4];
octave:4> 
octave:4>   [r, p, k, e] = residue (b, a)
r =

  -0.10000 + 0.45000i
  -0.10000 - 0.45000i

p =

  0.80000 + 0.40000i
  0.80000 - 0.40000i

k = [](0x0)

e =

  1
  1



The example is taken from the help and the answer is
incorrect.

Help .
