Mat Lab How To Mod

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.

The rem function produces a result that is either zero or has the same sign as the dividend. 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. The mod function is useful for congruence relationships.

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. For example when dividing 17 by three the remainder of two could be more important to know than the integer quotient of five. Instead mod a b returns an unevaluated symbolic expression if a is a symbolic polynomial and b is a real number.

The mod function produces a result that is either zero or has the same sign as the divisor. Rem x y for x y and y 0 has the same sign as x. Another difference is the convention when the divisor is zero.
