R = rem(X,Y)
R = rem(X,Y) if Y ~= 0, returns X - n.*Y where n = fix(X./Y). If Y is not an integer and the quotient X./Y is within roundoff error of an integer, then n is that integer. The inputs X and Y must be real arrays of the same size, or real scalars.
The following are true by convention:
rem(X,0) is NaN
rem(X,X) for X~=0 is 0
rem(X,Y) for X~=Y and Y~=0 has the same sign as X.
mod(X,Y) for X~=Y and Y~=0 has the same sign as Y.
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.
The rem function returns a result that is between 0 and sign(X)*abs(Y). If Y is zero, rem returns NaN.
