Problem with plot command in a for loop!

Hi there,

I've written a code which finally gives me an array, A. The code works fine and gives me the array correctly, but the problem is that I cannot plot it (I'm not sure if I should use plot command in the loop)! Could anybody help me with that please? Here is the code:

clear all
clc
i=0;

for t=0.05:0.05:10

      i=i+1;
      ksi=5;
      m=1;
      wn=2*pi/t;
      k=wn^2*m;
      U0=0;
      V0=0;
      dt=0.005;
      ag=load('BamL.txt');
      g=32.2;
      NBL(ksi,m,k,U0,V0,dt,ag,g);
      D(i,1)=max(ans(:,1));
      V(i,1)=D(i,1)*wn;
      A(i,1)=D(i,1)*wn^2;

end

figure
plot(t, A, 'r');
xlabel('Period');
ylabel('Accel');

After the for loop, your loop control variable t is going to keep its final value. When you get to the plot() call it is going to be a scalar. You need to duplicate the vector you listed in your for loop or you need to record each t value as you go through the loop and use that recorded value.
