∑_(u=1)^(su-2)▒∑_(v=1)^sv▒δ(i,j)...here the summation lower limit is u=1 and upper limit is su-2 similar to next summation form....i didnt know is my matlab R2009b contains symbolic tool or not. can u tel this equation in "for" loop.

What does F h ( u , v ) = i mean in the context of the delta function?
Does δ ( F h ( u , v ) = i , F h ( u + 1 , v ) = j ) mean the same as
1 if (Fh(u,v) == i & Fh(u+1,v) == j)
0 otherwise
?

It seems that the delta is the Kronecker Delta. In that case ou can make the following for-loop for this:
result=0;
for u=1:su-2
for v=1:sv
if Fh(u,v) == Fh(u+1,v)
result=result+1;
end
end
end
result
Make sure that the matrix Fh is defined beforehand
The value of 'result' after the loops is the answer of the double sum.
