x = [0:10:90]*pi/180;
x assumes 10 values.
After some codes, not giving here I have a matrix AR of size 8 x 10 complex double.Here 10 columns in AR correspond to x.
AR looks like this
Columns 1 through 6
-0.7907 - 0.0715i -0.9790 + 0.0019i -1.0042 + 0.0097i -0.2129 - 0.0251i 0.2552 + 0.0330i -1.4969 + 0.0031i

I want to extract each row of AR which comes a 1 x 10 size. what loops i will use here.
I am using this codes, but it gives wrong answer.
for ii = 1:numel(x)
for i=1:8;
Z(i)=abs(AR(i,ii));
end
end
What is wrong in above codes. I want to exract each rows of AR separtely.

What are you trying to do ? Do you want to compute the absolute value of each element in another matrix ?

I want to extract each row of AR which contains 10 values corresponds to x. There are 8 rows in AR.
Then I want to plot absolute value of each row versus x.

AR = num2cell(AR, 2);

I want to plot each AR1, AR2, AR3, ....,AR8 versus x, then how i do indexing, sir?

for ii = 1:size(AR,1)
V = AR(ii,:);
plot(V)
... save plot or whatever
end
Or simply plot all of the data as separate lines by tranposing the matrix:
plot(AR.')
