Can I use symsum function (summation) for an image matrix...or is it just applicable for numbers and variables etc?

An image matrix is just numbers and variables...

my code for an image matrix B(i,j) given below...is it correct...

syms i;

syms j;

A=symsum(symsum(xor(B(i,j),B(i-1,j)),j,0,1024),i,0,786);

I don't know is it?

What do you have and what is your goal? Edit your original question. I would guess symsum is not what you want.
