The mod function follows the convention that mod(a,0) returns a, whereas the rem function follows the convention that rem(a,0) returns NaN. Both variants have their uses. For example, in signal processing, the mod function is useful in the context of periodic signals because its output is periodic (with period equal to the divisor).

For vectors and matrices, mod finds the modulus after division element-wise. When both arguments are nonscalar, they must have the same size. If one argument is a scalar, the mod function expands the scalar input into an array of the same size as the other input. Find the modulus after division for the elements of two matrices.

m = mod(x,y) returns the modulus after division of x by y, where x is the dividend and y is the divisor. . This function is often called the modulo operation, which can be expressed as m = x - floor(x./y).

Jun 4, 2018 · The MATLAB documentation states that "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 produces a result that is either zero or has the same sign as the divisor. The rem function produces a result that is either zero or has the same sign as ...

Feb 9, 2024 · Learn more about mod operator I want to perform a mod operation on a number. ||10|| = 10 |||-10| = 10 Basically it returns the positive value of the input.

Apr 26, 2017 · I'm trying to plot an energy graph, and I'm having trouble plotting both the mod function. I don't understand why I cannot plot each point when mod(t,etime) == 0 and mod(t,ptime) == 0. The mod(t,etime) == 0 function only plots at the end, and I would like it to plot continuously.

Jan 7, 2022 · The modular inverse you desire exists as long as a and N are relatively prime. If not, then there is a problem. The trick in MATLAB is to use GCD. For example, suppose we wish to compute the modular inverse of 3, mod 7? That is equivalent to solving the problem

Aug 17, 2024 · you can also calculate the remainder after the division. 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.

Dec 3, 2020 · I would like to compute the following formula using MATLAB's mod function. My first five x0 values are 0,360000000000000 0,921600000000000 0,289013760000000 0,821939226122650 0,585420538734197 M value is fixed and is equal to 256.

Mar 6, 2018 · I have a short assignment for a MATLAB class and I am in need of a quick refresher and some help. SO The question states that i need to make an Array from 1 to 1000 and divide each of those numbers by an array of the prime numbers 2,3,5,7,11,13,17,23. and if the number in the first array is divisible by the prime number you add 1 to a final ...
