Mat Lab How To Mod

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.

The mod function produces a result that is either zero or has the same sign as the divisor. Starting in r2020b mod no longer finds the modulus for each coefficient of a symbolic polynomial. 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. Instead mod a b returns an unevaluated symbolic expression if a is a symbolic polynomial and b is a real number.

To find the modulus for each coefficient of the polynomial a use c t coeffs a. X and y are congruent mod m if and. Rem x y for x y and y 0 has the same sign as x. The rem function produces a result that is either zero or has the same sign as the dividend.

The concept of remainder after division is not uniquely defined and the two functions mod and rem each compute a different variation. The mod function is useful for congruence relationships. 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.
