I've just install Octave via Fink process on my PowerBook Ti 667 Mac OSX. As a test I use Ben Sapp 11 feb example :
octave:2> function xdot = f(x,t)
> xdot(1) = x(1) + x(2) + exp(-t);
> xdot(2) = x(1);
> endfunction
octave:6> x0 = [4;pi]
x0 =
4.0000
3.1416
octave:8> t = 3.5:0.05:20;
octave:9> x = lsode("f",x0,t);
octave:10> plot (t,x)
Everything works (I can print t & x ) except " plot (t,x) "
Can you help me to solve this issue ?
