How to do Scalar Division on a Matrix in R - Step by Step Examples

How to do Scalar Division on a Matrix in R ?

To perform scalar division on a matrix in R, you can use the division operator / with a matrix and a scalar value.

In this example,

We first create a 2x2 matrix named matrix1 using the matrix() function. We provide a vector of values c(4, 8, 6, 10) and specify the number of rows as 2.
Next, we define a scalar value scalar and set it to 2. This is the value by which each element of the matrix will be divided.
We then perform the scalar division operation by using the division operator / to divide matrix1 by scalar. The result is stored in a new variable called resultMatrix1.
Finally, we use the print() function to display the resulting matrix resultMatrix1.

matrix1 <- matrix(c(4, 8, 6, 10), nrow = 2)
scalar <- 2
resultMatrix1 <- matrix1 / scalar
print(resultMatrix1)

[,1] [,2]
[1,]  2   3
[2,]  4   5

In this example,

We first create a 3x3 matrix named matrix2 using the matrix() function. We provide a vector of values c(10, 20, 30, 40, 50, 60, 70, 80, 90) and specify the number of rows as 3.
Next, we define a scalar value scalar and set it to 5. This is the value by which each element of the matrix will be divided.
We then perform the scalar division operation by using the division operator / to divide matrix2 by scalar. The result is stored in a new variable called resultMatrix2.
Finally, we use the print() function to display the resulting matrix resultMatrix2.

matrix2 <- matrix(c(10, 20, 30, 40, 50, 60, 70, 80, 90), nrow = 3)
scalar <- 5
resultMatrix2 <- matrix2 / scalar
print(resultMatrix2)

[,1] [,2] [,3]
[1,]  2   8  14
[2,]  4  10  16
[3,]  6  12  18
