Characteristic polynomial
Description
Characteristic polynomial of a matrix.
Usage
characteristicPolynomial(A)
Arguments
A
a square matrix with numeric, character, or bigq entries
Value
A univariate qspray polynomial.
Examples
set.seed(666)
A <- matrix(rpois(9L, 10), nrow = 3, ncol = 3)
( P <- characteristicPolynomial(A) )
# check the roots are the eigen values:
f <- as.function(P, N = TRUE)
sapply(eigen(A)$values, f) # approx c(0, 0, 0)
