Mat Lab How To Mod

The mod function is useful for congruence relationships.

Mat lab how to mod. Another difference is the convention when the divisor is zero. X and y are congruent mod m if and. 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.

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. To find the modulus for each coefficient of the polynomial a use c t coeffs a. 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. 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.

Instead mod a b returns an unevaluated symbolic expression if a is a symbolic polynomial and b is a real number. The rem function produces a result that is either zero or has the same sign as the dividend. For example when dividing 17 by three the remainder of two could be more important to know than the integer quotient of five.
