A basic fact is that eigenvalues of a Hermitian matrix A are real, and eigenvectors of distinct eigenvalues are orthogonal. Two complex column vectors x and y of the same dimension are orthogonal if xHy = 0. ... Putting orthonomal eigenvectors as columns yield a matrix U so that UHU = I, which is called unitary matrix.
Are eigenvector matrices orthogonal?
In general, for any matrix, the eigenvectors are NOT always orthogonal. But for a special type of matrix, symmetric matrix, the eigenvalues are always real and the corresponding eigenvectors are always orthogonal.
Are the eigenvectors of a symmetric matrix orthogonal?
The eigenvectors of a symmetric matrix A corresponding to different eigenvalues are orthogonal to each other.
