Показать описание
Symmetric matrices have nice properties. We show that all the eigenvalues of a real symmetric matrix are real, and the eigenvectors corresponding to different eigenvalues are orthogonal. We further show the diagonalization and the spectral decomposition of a symmetric matrix.

The eigen basis is dual to the standard basis -- conjugacy is dual, spectral decomposition.
The integers are self dual as they are their own conjugates.
"Always two there are" -- Yoda.
Real is dual to imaginary -- complex numbers are dual.
Antipodal points identify for the rotation group SO(3) -- stereographic projection.
