Here is an example of using the mod() function to calculate the remainder after division for floating-point values in MATLAB: dividend = 5. This can be useful if you don’t have access to MATLAB Online and would like to do light work or run basic MATLAB code and Simulink models shared by others. Remainder After Division for Floating-Point Values Basic version of MATLAB Online: A basic version of MATLAB Online provides 20 hours per month of free use and access to 10 commonly used toolboxes. However, for positive X and Y, mod(-x,y) rem(-x,y)+y The mod function is useful for congruence relationships: x and y are congruent (mod m) if and only if mod(x,m) mod. So long as operands X and Y are of the same sign, the function mod(X,Y) returns the same result as does rem(X,Y). You can find the remainder after division by a negative divisor for a set of integers including both positive and negative values. mod(X,Y) always differs from X by a multiple of Y. Thread-Based Environment Run code in the background using MATLAB backgroundPool or accelerate code with Parallel Computing Toolbox ThreadPool. GPU Code Generation Generate CUDA code for NVIDIA GPUs using GPU Coder. If the divisor is positive the resulting array of the remainder is always positive.Įxample: Remainder After Division for Negative Divisor C/C++ Code Generation Generate C and C++ code using MATLAB Coder. You can also find the remainder of an array that has both positive and negative values using Matlab mod(). Matlab/Scilab equivalent Particular cases. The above code returns a new array, with the remainder of the corresponding element of array a.Įxample: Remainder After Division for Positive and Negative Values Scilab pmodulo can work with Complex values what Matlab mod can not. % calculate the remainder of each element You can also find the remainder of an array by dividing each element with a divisor. remainder – the output of the function, which is the remainder of the divisionĮxample: Find remainder using Matlab mod() % calculate remainderĮxample: Remainder After Division of an array.

divisor – the number that the dividend is being divided by.dividend – the number that is being divided.Syntax: Matlab mod() remainder = mod(dividend, divisor) Next, find the modulus of each coefficient in c divided by 10. This function is often called the modulo. The inputs X and Y must be real arrays of the same size, or real scalars. To evaluate the modulus for each polynomial coefficient, first extract the coefficients of each term using coeffs. m mod( x, y ) returns the modulus after division of x by y, where x is the dividend and y is the divisor. syms x a x3 - 2x + 999 mUneval mod (a,10) mUneval. The MATLAB documentation states that The concept of remainder after division is not. If one input arguments is nonscalar, then mod expands the scalar into a vector or matrix of the same size as the nonscalar argument, with all elements equal to the corresponding scalar. A general solution that behaves exactly like Matlab - also for negative and zero divisor. matlab rem functionDifference between mod and rem functions - MATLAB. All nonscalar arguments must be the same size. Due to the inexact representation of floating-point numbers on a computer, real (or complex) inputs may lead to unexpected results.Matlab mod() function is used to calculate the remainder after division. Find the modulus after division by for the polynomial. Calling rem for numbers that are not symbolic objects invokes the MATLAB rem function. Limitations Arguments X and Y should be integers. X and y are congruent (mod m) if and only if mod(x,m) = mod(y,m). The mod function is useful for congruence relationships: Remarks So long as operands X and Y are of the same sign, the function mod(X,Y) returns the same result as does rem(X,Y). mod(X,Y) always differs from X by a multiple of Y. Returns the remainder X - Y.*floor(X./Y) for nonzero Y, and returns X otherwise. Modulus (signed remainder after division) Mod (MATLAB Function Reference) MATLAB Function Reference
