CharacteristicPolynomial
gives the characteristic polynomial for the matrix m.
CharacteristicPolynomial[{m,a},x]
gives the generalized characteristic polynomial with respect to a.
Details
- m must be a square matrix.
- It can contain numeric or symbolic entries.
- CharacteristicPolynomial[m,x] is essentially equivalent to Det[m-id x] where id is the identity matrix of appropriate size. »
- CharacteristicPolynomial[{m,a},x] is essentially Det[m-a x]. »
