It seems unlikely that that is complete and exact error message. Please copy and paste the complete error traceback.

??? Attempted to access CORR.%cell.%cell(65,64); index out of bounds because size(CORR.%cell.%cell)=[3,3].

Error in ==> Untitled1 at 26

CORR{1}{d,1}(R(i,j),R(i,j+d))=CORR{1}{d,1}(R(i,j),R(i,j+d))+1;

The error message seems to be clear. The problem does not concern the CORR function, but accessing the variable CORR:

 CORR{1}{d,1} is a [3x3] array, but you want to access the index [65,64]

You can use the debugger to find the cause of this problem:

dbstop if error

thanks jan simson

but i don't have any knowledge about the debugger. do u mean MATLAB debug option through which we run the program?

You probably want normxcorr2(), or less likely xcorr2(). You're trying to roll your own and messing up.
