Reduction of the Symmetric Eigenproblem Ax=λBx and Related Problems to Standard Form
In many fields of work the solution of the eigenproblems Ax=λBx and ABx=λx (or related problems) is required, where A and B are symmetric and B is positive definite. Each of these problems can be reduced to the standard symmetric eigenproblem by making use of the Cholesky factorization  of B.
