Consider a vector containing random variables such as the following:
y=rand(10,1);
How can I evaluate the autocorrelation between all the components of the vector? I want to obtain the 10x10 autocorrelation matrix of the vector.

Hello Mohamad,
MATLAB’s auto correlation function can be used for this purpose.
The following is a sample code on how you would use it
y=rand(10,1); %derfine a random vector
[acf,lags,bounds] = autocorr(y) %autocorrelate the vector
plot(acf) %plots the autocorrelated vector
