Abstract
Unsymmetric matrices are not uncommon in large-scale structural analysis. In panel flutter analysis, for example, one has to deal with unsymmetric equations due to the appearance of the unsymmetric aerodynamic influence matrix. When large deflections and unsteady third-order piston theory aerodynamics are considered in the flutter analysis, it is necessary to solve the unsymmetric equations incrementally and/or to solve the unsymmetric generalized eigen-problems interactively. Thus, an efficient and accurate unsymmetric equation solver plays an important role in structural analysis.
