Yes, of course. Sorry for thinking that it's
something
general and somebody can answer it without seeing the
code...
So the code is:
> % Input variables:
> clear all
> N = 2;
> icrf = 0.01;
> elf = -5;
> vef = 5;
> icr = 0.01;
> el = -4*pi;
> ve = 4*pi;
>
> % Opening a file for data to be written.
>
> la = fopen('/home/dat/N2.5n4n01.dat', 'wt');
>
> %%%%%%%%%%% Begining of Iteration %%%%%%%%%%%%%
>
> for f = elf:icrf:vef
> zfp = 0;
>
> for k = el:icr:ve
>
> a(1) = k;
> a(2) = 2*a(1) - N*f*cos(a(1));
>
> for m = 2:(N-1)
> a(m+1) = 2*a(m) - a(m-1) -
> -N-m+1)*f*cos(a(m));
> end
> zfn = a(N-1) + f*cos(a(N)) - a(N);
> if
> (zfn*zfp < 0)
> a0 = (a(1) + b)/2;
> fprintf(la, '%f %f\n', a0,f);
> end
>
> b = a(1);
> zfp = zfn;

> end

That is. Nothing special, and the result is as it
should be, I just don't understand what is this
report
then:
error: can't perform indexing operations for <unknown
type> type
I'm quite new to octave, before I had used some
Matlab, and I guess it would be OK on that...
Any guess?
Thanks
