Definite matrix
text:
In mathematics, a symmetric matrix M with real entries is positive-definite if the real number x ⊤ M x is positive for every nonzero real column vector x , where x ⊤ is the row vector transpose of x . More generally, a Hermitian matrix is positive-definite if the real number z ∗ M z is positive for every nonzero complex column vector z , where z ∗ denotes the conjugate transpose of z . Positive semi-definite matrices are defined similarly, except that the scalars
