searching for the particular point value from the two different data sets

I am trying to search and extract the particular point values (at some coordinates) from two different datasets but the problem is the index numbers in both datasets are different. I am comparing the data for the particular points so it might be same for the same coordinates but not for the same index. How can I compare them?

Without more detail about how your dataset is structured (e.g. do you have two vectors, or arrays, or tables?), it is not possible to give specific suggestions.

Generically, you might find the ismember and intersect functions useful.
