I'm trying to find an answer of an mathematics operation to find a difference in two different black and white images, and the answer is coming as an matrix and i only need a single value.... what can i do? and how i can take two values for different conditions (equal pr not equal) if the answer is coming as matrix with different number of ones at each time?

" and how i can take two values for different conditions (equal pr not equal) if the answer is coming as matrix ...?"
Well, the short answer is
truefalse=all(yourDifferenceArray); % only a single pixel is noted as a difference
truefalse=any(yourDifferenceArray); % takes every pixel to be different for TRUE
Or, of course, you could have some threshold of how many must be different to count by
truefalse=sum(yourDifferenceArray)<ThresholdNumber;
This assumes the difference is the plain subtraction so '==' returns 1 (TRUE) for locations that are the same.
