发帖数: 752 | 1 I have a matrix and it turns out
if lambda is eigenvalue, 2-lambda is also eigenvalue
is this a kind of symmetry? does it help solving the eigenvalue problem?
for example, does this property help in decomposing the matrix? | c*******h
发帖数: 1096 | 2 if lambda is eigenvalue, 2-lambda is also eigenvalue
if 2-lambda is eigenvalue, 4-lambda is also eigenvalue
if 4-lambda is eigenvalue, 8-lambda is also eigenvalue
if 8-lambda is eigenvalue, 16-lambda is also eigenvalue
...
how many eigenvalues do you have? | n*s
发帖数: 752 | 3 if 2-lambda is e-value, 2-(2-lambda)=lambda is also e-value
