How to calculate auto-correlation for multiple columns?

Hi,

The attached code can be used to calculate auto correlation of data sets in one column. I have to calculate auto correlation for 12 column (yearly data). How to modify this code for attached data set A?

So you got this code from somewhere and expect someone here to read it and understand it for you and then modify to your needs?

Isn't it a little too much to ask for? Why don't you try it yourself and show us the difficulties you are facing and ask specific questions.

Dear KL,

Thanks for valuable suggestion. I am not good in Matlab.I tried my best and spent almost one week but I did not got good results. An expert in coding can consume just 5 to ten minutes to solve it or at least guide me with some suitable reference. I will appreciate if You can suggest me some reference links regarding autocorrelation of multiple variables.
