About this document

Transforming Generalized Eigen-Problem by wnjue001 is a document available to read on EtoBox.

The document discusses three methods for efficiently transforming a generalized eigenproblem (where the stiffness and mass matrices are symmetric but the mass matrix may be indefinite) into a standard eigenproblem (where both matrices are symmetric positive definite). Method 1 inverts the mass matrix, but this results in a nearly dense and unsymmetric transformed matrix. Method 2 factors the mass matrix using Cholesky decomposition, allowing the problem to be solved without explicitly forming the dense tr
