Dear sir/madam,
I am unable to repeat the x,z,c,b value simultaneously. I have attached the final plot to be obtained.
Please look into the problem
Thank you

You did not attach the file.
When I search on that file name, I find a number of different science papers.

%you have a problem. X was just created as 330 x 330, but X1 is 1 x 1361.
%Even if we had only created X as 330 x 1 or 1 x 330 then we would have a
%problem.
newx= X1+X;
Arrays have incompatible sizes for this operation.
newz= Z1+x;
plot(newx, newz)
Maybe you mean X1+x like you have for Z1 ? Speaking of which, wouldn't Z1 + z make more sense for z values?
Anyhow, it is not obvious to me what out of what you calculated (X, Z, B, C) that you want to plot against what. And if you look at the shapes in those variables... are you sure that is what you are expecting with increasing i values?
