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
