H-2 model reduction for large-scale linear dynamical systems
(Siam Publications, 2008)
The optimal H-2 model reduction problem is of great importance in the area of dynamical systems and simulation. In the literature, two independent frameworks have evolved focusing either on solution of Lyapunov equations ...
Recycling BICG with an application to model reduction
(Siam Publications, 2012)
Science and engineering problems frequently require solving a sequence of dual linear systems. Besides having to store only a few Lanczos vectors, using the biconjugate gradient method (BiCG) to solve dual linear systems ...
