Nondefective Complex Symmetric Matrices,g complex vectors x ≠ 0 such that . . A complex nxn matrix A ≡ (a.), 1 ≤ i,j ≤ n, is complex symmetric if and only if for every i and j, a. = a.. A complex symmetric matrix is nondefective if and only if it has a complete set of eigenvectors.

Factored Inverses, Real Symmetric Block Lanczos, resulting factorization of the associated B matrix is also sparse. An eigenvalue is extreme if it is one of the algebraically-smallest or the algebraically-largest eigenvalues in the eigenvalue spectrum.
