Dear Octave expert:
I follow the simple program in book "Matlab for Engineers"
by Adrian Biran
and
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

%VECROT Animation program which shows a rotating vector
% defined as a complex number
f = 50; % frequency, Hz
omega = 2*pi*f; % angular frequency, rad/s
tmax = 1/50; % time for a complete rotation, s
time = [ ];
motion = [ ];
axis('square')
axis([-1 1 -1 1])
for t=0: tmax/36: tmax
z = exp(i*omega*t); %complex number description
x = real(z); % Cartesian projections
y = imag(z);
time = [ time t];
motion = [motion y];
plot([0, x], [0, y])
pause(1.0)
end
