## Re: Plotting problem

```I am sending some of the code that is relevant here.
Please note that it  is computing the values of V at
the higher n. It is simply not plotting it. I am using
Octave 2.1.5 with GNU Plot 4.1

for n = 1: 5000
calling function A
Calling function B
calling function C

if n == 1
z = V;
c = 'r';
elseif n == 1000
z1 = V;
c = 'b';
elseif n == 5000
z2 = V;
c = 'm';
end
end

hold on
x = linspace (0,1,N);
X = x/lambda ;
y = z/Vo;
y1 = z1/Vo;
y2 = z2 /Vo;
plot (X,y,'r')
plot (X,y1,'b')
plot(X,y2,'m')
print ('filename.pbm','-dpbm')
hold off

So when n is increased from 5000 to 25000
and I try to get at three points, n = 1, n= 10000 and
n = 25000, it is leaving out the n = 10000 plot but it
does calculate the value of V for that.
INcidentally, I have written this code originally for
MATLAB and could iterate upto very large n without any
problems.
I will greatly appreciate your help.
Thanks

Goals too clearly defined can become blinkers.
