Question

I am proper stuck on plotting a graph.

It’s a graph of flow simulation, I need to be able to see the graphs for about 25 time segments between t=0 and t=1.

this is the code I’ve written that does it for t=0.1. I obviously can’t repeat the code 25 times. Is there any way of programming it to plot all in one go. i.e using loop?

ALSO, I need to redefine both the axis to go from 0 to 1.

Many thanks

Answer 1

t=linspace(0,1,25)
for k=1:length(t)

  A=(a1^2*P)/(i*mu*L*alpha^2)

  B1=i^1.5*alpha*r/a1

  B2=i^1.5*alpha

  B11=besselj(0,B1)

  B22=besselj(0,B2)

  B=1-(B11/B22)

  C=exp(i*w*t(k))

  u=real(A*B*C)

  plot(u,r,u,-r)
  drawnow
end

use drawnow after your plot command. this will force matlab to draw the plot immediately, enabling you to see the progress of the simulation.

EDIT:
I didn’t see the last bit. To set your x & y axis to go from 0 to 1, do xlim([0 1]) and ylim([0 1])
