Determinant value of symmetric matrix
WebA NOTE ON SKEW-SYMMETRIC DETERMINANTS by WALTER LEDERMANN (Received 9th Augus 1991t ) A shor prooft base, d on the Schur complement, is given of the classical result that the determinant of a skew-symmetric matrix of even order is the square of a polynomial in its coefficients. 1991 Mathematics subject classification: 15A15 Let (0 a1 … WebA symmetric matrix with real values is also a normal matrix. Since symmetric matrices are a special case of Hermitian matrices, all the eigenvalues of a symmetric matrix are real numbers. The spectral theorem tells us that all matrices whose elements are real are diagonalizable matrices and, furthermore, the diagonalization is done by means of ...
