Find the power of a matrix in R (original) (raw)

Last Updated : 5 Apr, 2021

In this article, we are going to see how to compute the power of a matrix in R Programming Language. Matrix is an arrangement of numbers into rows and columns.

Different ways of finding the power of matrix in R programming:

• By using %^%.
• By using a power function.

Method 1: By using %^%

Before using this we need to import expm library into our R studio.

Installing expm library into R studio:

Step 1: First you need to select tools.

Step 2: After selecting the tool you need to press install packages:

Below is the implementation:

We Import the expm and assigned values into the mat by using the matrix function. After that, we are finding the power of the matrix.

R `

loading expm library

library(expm)

creating mat variable and storing

matrix into it.

mat <- matrix(1:9, nrow=3)

In matrix function data will fill column wise,

here data will be 1 to 9 as we mentioned 1:9

and rows will be 3 as we given nrows as 3

finding power of matrix here power is 4

mat %^% 4

`

Output:

Method 2: By using a power function.

For using the power function we need to install matrixcalc package into our Rstudio

Below is the implementation:

Here we import the matrixcalc and assigned values into the mat by using matrix function. After that, we are finding the power of matrix by using power function.

R `

loading package

require(matrixcalc)

creating matrix.

a<- matrix(1 : 9, nrow = 3)

finding power of matrix by using power function.

In matrix function data will fill column wise,

here data will be 1 to 9 as we mentioned 1:9

and rows will be 3 as we given nrows as 3

matrix.power(a, 9)

`

Output:
