Dear Eike, Thank you so much, the simple slicing operation solved my problem. Thank you for the links, i am just going through the same.
Dave I wanted was to extract a matrix of dimension 330,330 from a matrix of dimension 550,550. Sorry if my previous post was not clear. I am able to do it by slicing as suggested by Eike.
