From http://www.mathworks.com/help/matlab/ref/rem.html the Tips section:
rem(X,Y) and mod(X,Y) are equal if X and Y have the same sign, but differ by Y if X and Y have different signs.
Definitions: R = rem(X,Y) if Y ~= 0, returns X  n.*Y where n = fix(X./Y). B = fix(A) rounds the elements of A toward zero, resulting in an array of integers. M = mod(X,Y) if Y ~= 0, returns X  n.*Y where n = floor(X./Y). B = floor(A) rounds the elements of A to the nearest integers less than or equal to A.
