Returns the minor of element (i,j) of the square matrix A, i.e., the determinant of the
sub-matrix that results when row i and column j are deleted.
Arguments
- A
a square matrix
- i
row index
- j
column index
Value
the minor of A[i,j]
Examples
M <- matrix(c(4, -12, -4,
2, 1, 3,
-1, -3, 2), 3, 3, byrow=TRUE)
minor(M, 1, 1)
#> [1] 11
minor(M, 1, 2)
#> [1] 7
minor(M, 1, 3)
#> [1] -5
