Interim users' guide to Eigen problem program LMKA (IM-MATH-004)

Program LMKA is an alternative to the AA9 series of programs (Ref 2) and finds the eigenvalues and eigenvectors associated with the differential equations: , for up to 20 velocities. Optionally damping and undamped natural frequency are plotted against velocity, this plotting being restricted to a maximum of 15 velocities.
