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?

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.
