Can non-symmetric matrix be positive definite?
Can non-symmetric matrix be positive definite? Therefore we can characterize (possibly nonsymmetric) positive definite ma- trices as matrices where the symmetric part has positive eigenvalues. By Theorem 1.1 weakly positive definite matrices are also characterized by their eigenvalues. Are positive definite matrix symmetric? A positive definite matrix is a symmetric matrix with all positive eigenvalues. […]
