The eigenvalues A; of A — XB and the eigenvalues A; of A — XB are related by Xi = (3Xi/(l — a A;). 2. If A and B are non-Hermitian, but A = aSAT and B = (3SBT are Hermitian, with B positive definite, for easily determined a, f3 and nonsingular S and T, then one can compute the eigenvalues A and eigenvectors x of A — XB. One can convert these to eigenvalues A and eigenvectors x of A via A = A/3/a and x = Tx. , A* = — ^4), then \J~-\A is Hermitian, so we may choose a = \/—T, (3=1, and S — T = I. 5 for further discussion.

If A is non-Hermitian, but A = aSAS~l is Hermitian for easily determined a and 5, it may be advisable to compute the eigenvalues A and eigenvectors x of A. One can convert these to eigenvalues A and eigenvectors x of A via A = A/a and x — S~lx. , A* = —A) by the constant V^-T makes it Hermitian. 5 for further discussion. 2. 4. Suppose B is ra by n, so A is n by n. Generally speaking, if A is about as small or smaller than B (n < m, or just a little bigger), the eigenproblem for A is usually cheaper than the SVD of B.
