how to compute and plot results for three different frequency vector ?

hello ,

i want to use three different frequency vectors and want to plot their results in same graph how should i do this ?

first i want to compute w1 = [2*pi*90 2*pi*110];

second is w2= [2*pi*130 2*pi*150];

third is w3 = [2*pi*190 2*pi*210];

i have written a code for computing only 1 vector

******************

w1 = [2*pi*190 2*pi*210];

m = length(w1);

Aik = zeros(2,2,m);

Bik = zeros(2,1,m);

Cik = zeros(1,2,m);

for i = 1:m

Aik(:,:,i) = [0 1; -w1(i)^2 0];

Bik(:,:,i) = [0 w1(i)^2];

Cik(:,:,i) = [1 0];

end

*************************

how should i again compute w2 and w3 in the same m file and plot result in one graph for w1, w2,w3 ?

how should i compute w1 then w2 and w3 and plot their result in same m file ?

hi, you can plot your three signals in the same graph using subplot command as this example :

 r1=randn(100,1);
 r2=rand(100,1);
 r3=r1+r2;
 subplot(1,3,1)
 plot(r1)
 subplot(1,3,2)
 plot(r2)
 subplot(1,3,3)
 plot(r3)

So the command subplot has the structure subplot(Line,Column, Position) .
