Mat Lab How To Mod

Another difference is the convention when the divisor is zero.

The rem function produces a result that is either zero or has the same sign as the dividend. The mod function produces a result that is either zero or has the same sign as the divisor. Mod x y and rem x y are equal if x and y have the same sign but differ by y if x and y have different signs. Mod x y for x y and y 0 has the same sign as y.

Instead mod a b returns an unevaluated symbolic expression if a is a symbolic polynomial and b is a real number. B mod a m returns the remainder after division of a by m where a is the dividend and m is the divisor this function is often called the modulo operation which can be expressed as b a m floor a m the mod function follows the convention that mod a 0 returns a. To find the modulus for each coefficient of the polynomial a use c t coeffs a. One of the thousands of built in functions in the mathematical software program matlab is the mod command short for modulus the mod function directly computes the remainder of a division operation.

Rem x y for x y and y 0 has the same sign as x. X and y are congruent mod m if and. The mod function is useful for congruence relationships.
