mod function in Matlab

MATLAB is a powerful environment widely used for scientific fields. There are various built-in functions of MATLAB used to perform mathematical operations on arrays and matrices. One such function is mod() which stands for modulus. The mod() function returns the remainder value after dividing two numbers. The mod() function produces a result that is zero or a value with the same sign as the divisor. In this comprehensive guide, we will learn the usage of the mod() function in MATLAB.

What is mod() Function in MATLAB

The mod() function in MATLAB returns the remaining value when two numbers are divided. The format for using the mod() function in MATLAB is:

result = mod(a, b)

Example 1

Consider the following example for dividing the two numbers 27 and 5. This function returns the remainder of these two numbers:

b = mod(27,5)

Example 2

You can determine the modulus after dividing the row vector by a number. The following example illustrates the division of a matrix with the number 2:

a = [4:15];
b = 2;
R = mod(a,b)

Example 3

The following example demonstrates the usage of the mod() function when the column vector and row vectors are divided from each other:

a = [8; 9; 10; 11];
b = [2: 3];
R = mod(a, b)

Example 4

Consider the following example to find the mod of a square matrix in MATLAB:

a= [13 8 7 -8; 67 22 12 3; 41 2 15 15; 5 3 31 21];
b= [1 2 3 -5; 4 3 2 1; 2 3 4 5; 5 3 2 1];
R = mod(a, b)

Bottom Line

The mod() function in MATLAB is important in solving problems related to number division, indexing, and data mapping. This function returns the remaining value after dividing the two numbers. We have discussed the usage of the mod() function in MATLAB on different matrix numbers. By understanding the significance and applications of the mod() function, users can leverage its capabilities to tackle a wide range of mathematical and computational challenges in MATLAB.
