Abstract

The authors present a simple method for obtaining eigenvectors of a real symmetric matrix. Especially when there are only two unequal eigenvalues of real symmetric matrix A,One eigenvalueλ is arbitrarily selected,the corresponding homogeneous linear equations are solved( λI- A)X = 0,then,all eigenvectors of matrix A can be solved.
