In [[numerical analysis]] and [[linear algebra]], the '''Inverse eigenvalues theorem''' states that, given a matrix A that is [[nonsingular]], |with [[eigenvalue]] <math>\lambda|>0</math>, <math>\lambda</math> is an [[eigenvalue]] of <math>A</math> if and only if <math>\lambda^{-1}</math> is an eigenvalue of <math>A^{-1}</math>.
