template<class ScalarType, class MV>

std::vector<int> Anasazi::Eigensolution< ScalarType, MV >::index

An index into Evecs to allow compressed storage of eigenvectors for real, non-Hermitian problems.

index has length numVecs, where each entry is 0, +1, or -1. These have the following interpretation:

• index[i] == 0: signifies that the corresponding eigenvector is stored as the i column of Evecs. This will usually be the case when ScalarType is complex, an eigenproblem is Hermitian, or a real, non-Hermitian eigenproblem has a real eigenvector.
• index[i] == +1: signifies that the corresponding eigenvector is stored in two vectors: the real part in the i column of Evecs and the positive imaginary part in the i+1 column of Evecs.
• index[i] == -1: signifies that the corresponding eigenvector is stored in two vectors: the real part in the i-1 column of Evecs and the negative imaginary part in the i column of Evecs
