WebProperties of real symmetric matrices I Recall that a matrix A 2Rn n is symmetric if AT = A. I For real symmetric matrices we have the following two crucial properties: I All eigenvalues of a real symmetric matrix are real. I Eigenvectors corresponding to distinct eigenvalues are orthogonal. I To show these two properties, we need to consider complex matrices of type … WebAn important point to understand is that not all symmetric matrices are invertible.
