Dmitri,

  While not an octave-specific question, perhaps you can point me toward
understanding why my results are so different from yours. I used a simple,
3x3, matrix from my book:

octave:1> a = load("sample.dat")
a =

  1.00000  0.33300  0.50000
  3.00000  1.00000  3.00000
  2.00000  0.33300  1.00000

octave:2> b = eig(a)
b =

   3.05294 + 0.00000i
  -0.02647 + 0.40362i
  -0.02647 - 0.40362i

  Instead of seeing values as in your example, I have the above. What is it
telling me?

Thanks,

Rich
