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 [1] -185

**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 [1] -185
