WebDec 19, 2012 · Eigenvalues of hermitian (real or complex) matrices are always real. But what if the matrix is complex and symmetric but not hermitian. In hermitian the ij element is complex conjugal of ji element. But I am taking about matrix for which ij element and ji element are equal. Eigen values of such a matrix may not be real. WebYes, say v is an eigenvector of a matrix A with eigenvalue λ. Then Av=λv. Let's verify c*v (where c is non zero) is also an eigenvector of eigenvalue λ. You can verify this by computing A(cv)=c(Av)=c(λv)=λ(cv). Thus cv is also an eigenvector with eigenvalue λ. I wrote c as non zero, because eigenvectors are non zero, so c*v cannot be zero.
