Dear Octave expert:

    I follow the simple program in book "Matlab for Engineers"
by Adrian Biran

    Moshe Breiner
                     published by Addison Wesley
page 185 figure 4.10

but called in octave2.0.14, it response error , around the axis,

with attached program.

   hope to see your help and thanks in advance
