I want to guess outside the given data! For example data x = 1:5 y = [7 9 10 11 12] are given. And I want to guess the values at x=6,7. (For any method) How can I do it? Help me..

>> interp1(x,y,[6,7],'linear','extrap')
ans =
13 14
And remember that extrapolated values are always to be taken with a pinch of salt.
