WebPositive definite matrix. by Marco Taboga, PhD. A square matrix is positive definite if pre-multiplying and post-multiplying it by the same vector always gives a positive number as a result, independently of how we choose the vector. Positive definite symmetric matrices have the property that all their eigenvalues are positive.
