for n =1:N
for radius = 1:R
% Random x & y numbers.
theta = rand(1,n)*(2*pi);
r = sqrt(rand(1,n))*radius;
end
x(n)= x1 + r.*cos(theta);
y(n)= y1 + r.*sin(theta);
end
plot(x,y,'.')
i am creating a random plot inside a circle using for command. i am having an error:
??? In an assignment A(I) = B, the number of elements in B and
I must be the same.
Error in ==> Q11 at 53
x(n)= x1 + r.*cos(theta);
how can i overcome this?

Just like the error says the number of elements in B and in I must be the same. For you, B is
x1+r.*cos(theta)
with the number of elements being equal to the number of elements in r and I is
n
with 1 element.
Are you sure you want
theta = rand(1,n)*(2*pi);
r = sqrt(rand(1,n))*radius;
and not
theta = rand*(2*pi);
r = sqrt(rand)*radius;
