no use of for loop

Hi!

 n=[0:0.01:0.5]; 
  f=[2:0.01:3];
    for k=1:length(n)

    for l=1:length(f)
        beta=n(k).*Dc/Dw
    omega=2e9*pi*f(l);
    epsilon=3./(1+j*omega*tau);

    epsilon_k(k,l)=(beta*(epsilon)+(1-beta)(epsilon_cc));
end 
end

is there any advice to programm this without using for loops?

Thank you

EDIT CORRECTED PROGRAM:

Hi sorry. here is the corrected program.

 n=[0:0.01:0.5]; 
  f=[2:0.01:3];
epsilon_cc=2
    for k=1:length(n)

    for l=1:length(f)
        beta=n(k);
    omega=2e9*pi*f(l);
    epsilon=3./(1+j*omega*tau);

    epsilon_k(k,l)=(beta*(epsilon)+(1-beta)*(epsilon_cc))
end 
end

thank you for your help!

What are sizes of Dc , omega

[Wayne King]

You should make your post so that people can actually execute your code. You do not give Dc, or Dw, and what is this line

   epsilon_k(k,l)=(beta*(epsilon)+(1-beta)(epsilon_cc));

are you multiplying 1-beta and epsilon_cc?

The variable "epsilon" does not change its value inside the loop, so move its calculation out of the loop.

"beta" does not change its value inside the inner loop, so move to the outer loop.

The variables "j", "epsilon_cc", "Dc" and "Dw" are not defined in the code snippet. We cannot guess their values or if they are functions.

The expression "(1-beta)(epsilon_cc)" is not valid in Matlab. Perhapos you forgot a "*".

Please cleanup the code at first.
