# Getting the Determinant of the Matrix in R Programming – det() Function

`det()` function in R Language is used to calculate the determinant of the specified matrix.

Syntax: det(x, …)

Parameters:
x: matrix

Example 1:

 `# R program to illustrate ` `# det function ` ` `  `# Initializing a matrix with ` `# 3 rows and 3 columns ` `x <``-` `matrix(c(``3``, ``2``, ``6``, ``-``1``, ``7``, ``3``, ``2``, ``6``, ``-``1``), ``3``, ``3``) ` ` `  `# Getting the matrix representation ` `x ` ` `  `# Calling the det() function ` `det(x) `

Output:

```     [, 1] [, 2] [, 3]
[1, ]    3   -1    2
[2, ]    2    7    6
[3, ]    6    3   -1

Example 2:

 `# R program to illustrate ` `# det function ` ` `  `# Initializing a matrix with ` `# 3 rows and 3 columns ` `x <``-` `matrix(c(``3``, ``2``, ``6``, ``-``1``, ``7``, ``3``, ``2``, ``6``, ``-``1``), ``3``, ``3``) ` ` `  `# Getting the matrix representation ` `x ` ` `  `# Getting the transpose of the matrix x ` `y <``-` `t(x) ` `y ` ` `  `# Calling the det() function ` `det(y) `

Output:

```     [, 1] [, 2] [, 3]
[1, ]    3   -1    2
[2, ]    2    7    6
[3, ]    6    3   -1

[, 1] [, 2] [, 3]
[1, ]    3    2    6
[2, ]   -1    7    3
[3, ]    2    6   -1
