i want to see each plot figure for every j i have, so how can i do it?

L=5;

R=20;

i_0=0.5;

v=5;

dt1=[0.1,0.01,0.001];

for j=length(dt1)

dt=dt1(j)

t=[0:dt:1];

N=length(t);

i_bd(1)=i_0;

for k=2:N

i_bd(k)=(dt*v/L+i_bd(k-1))/(1+R/L*dt);

end

i_fd(1)=i_0;

for k=1:N-1

i_fd(k+1)=dt*v/L-i_fd(k)*(dt*R/L-1);

end

figure(j); plot(t,i_bd,t,i_fd,'LineWidth',2)

% right here I wish I could see each figure for every j, right now it only prints out plot for j=3

xlabel('Time [s]')

ylabel('Current [A]')

legend('i backward','i forward')

end

Answer 1

Your for loop states j = length(dt1), which is 3 in your case. So the for loop only do figure 3 for you.

Use the following instead.

for j=1:length(dt1)

thank you so much!

Instead of

figure(j)

just simply do

figure;

to bring up a totally new figure window.

[Quynh Tran]

it returns 1 figure (figure 1) only for j=3, figures for j=1 and j=2 are not showing. I tried hold on too but still doesn't work
