Now assume to be symmetric with non-zero off-diagonal elements, i.e. , . Let be the eigenvalues and the normalized eigenvectors of T, i.e. We consider the inverse problem: Determine from and . It is ...

val = EIGVAL(a); print val; Notice that since a is not symmetric the eigenvalues are complex. The first column of the VAL matrix is the real part and the second column is the complex part of the three ...
