Which Eigenvalues
The selective eigenvalue calculation determines eigenvalues close to the reference point using one of
three different measures for closeness. The options are:
• Smallest Magnitude w.r.t RP; If this option is selected, the selective eigenvalue calculation chooses
eigenvalues that are closest to the reference point by magnitude of the eigenvalue.
• Smallest Imaginary Part w.r.t RP; If this option is selected, the selective eigenvalue calculation
chooses eigenvalues that are closest to the reference point using only the imaginary part of the
eigenvalue.
• Smallest Real Part w.r.t RP; If this option is selected, the selective eigenvalue calculation chooses
eigenvalues that are closest to the reference point using only the real part of the eigenvalue.
