The '''characteristic polynomial''' of a square [[matrix]] <math>A</math> is given by,

:<math>|A-\lambda I|=0</math>

:<math>f(\lambda) = \det(A-\lambda I)</math>

where <math>I</math> is the [[identity matrix]].

where <math>I</math> is the [[identity matrix]]. The zeros of this polynomial are the eigenvalues of the matrix.
