can some one give me a script that calculat beta

I need a scipte that calculat beta or at least turn the signal into a matrix

If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks). If your main issue is with understanding the underlying concept, you may consider contacting the authors.

The way you stated your question the answer is simply this:

beta=(sigma1/sigma2)^2;

If you want a more meaningful answer have a read here and here. It will greatly improve your chances of getting an answer.

Thank u sir for your help, i have already created the script for that at the end.

HM = hankel(f); %turn signal f into Hankel matrix
[U,S,V] = svd(HM); %Singular value decomposition of the matrix SVD
DD=diag(S); %get diagonals D from symbolic matrix
bbt=(DD(1)/DD(2))^2; %calculat the scale parameter beta
