An evaluated expression is true when the result is nonempty and contains all nonzero elements (logical or real numeric). Otherwise, the expression is false.
The A==B is not true because there is at least one element that does not match. The A=~B is not true because there is at least one element that does match. So you get the third possibility.

A and B are matrices not scalar compare them using isequal. Try this
if isequal(A,B)
% do something
elseif ~isequal(A,B)
% do something
And to know what you did wrong in your code type this:
A==B
