Determinant of a matrix in r
WebSep 17, 2024 · The characteristic polynomial of A is the function f(λ) given by. f(λ) = det (A − λIn). We will see below, Theorem 5.2.2, that the characteristic polynomial is in fact a polynomial. Finding the characterestic polynomial means computing the determinant of the matrix A − λIn, whose entries contain the unknown λ.
