Hi , Could you please help to simplify the following code. I created a symmetric Toeplitz matrix where its eigenvalues [ 0.28878, 1.7141].

I want the same matrix, so can we create it in a simple way. For example, can we get the same matrix when we just multiply a scalar by toeplitz(R)?

N=200;
Ns=1:N;
R=1./Ns;
D=toeplitz(R);
B=D+3*pi/7 *eye(N);
A=1/6 * B;
s=eig(A)

A = toeplitz(R)/6+pi/14*eye(N)

A trivial simplification of your code, but I doubt that it is possible to do much better.
