#### Preconditioning Parametrized Linear Systems

Preconditioners are generally essential for fast convergence in the iterative solution of linear systems of equations. However, the computation of a good preconditioner can be expensive. So, while solving a sequence of ...

#### NONLINEAR PARAMETRIC INVERSION USING INTERPOLATORY MODEL REDUCTION

(Siam Publications, 2015-01-01)

#### Inexact solves in interpolatory model reduction

(Elsevier Science Inc, 2012-04-15)

#### Model Reduction by Rational Interpolation

(Siam, 2016-07-01)

The last two decades have seen major developments in interpolatory methods for model reduction of large-scale linear dynamical systems. Advances of note include the ability to produce (locally) optimal reduced models at ...

#### Model Reduction for Systems with Inhomogeneous Initial Conditions

We consider the model reduction problem for linear time-invariant dynamical systems having nonzero (but otherwise indeterminate) initial conditions. Building upon the observation that the full system response is decomposable ...

#### Interpolatory methods for $\mathcal{H}_\infty$ model reduction of multi-input/multi-output systems

(Springer, 2016-08-01)

We develop here a computationally effective approach for producing high-quality $\mathcal{H}_\infty$-approximations to large scale linear dynamical systems having multiple inputs and multiple outputs (MIMO). We extend an ...

#### Damping optimization of parameter dependent mechanical systems by rational interpolation

We consider an optimization problem related to semi-active damping of vibrating systems. The main problem is to determine the best damping matrix able to minimize influence of the input on the output of the system. We use ...

#### COMPUTING REDUCED ORDER MODELS VIA INNER-OUTER KRYLOV RECYCLING IN DIFFUSE OPTICAL TOMOGRAPHY

(Siam Publications, 2017-01-01)

#### Data-driven structured realization

(Elsevier Science Inc, 2018-01-15)

#### Interpolatory Model Reduction of Parameterized Bilinear Dynamical Systems

Interpolatory projection methods for model reduction of nonparametric linear dynamical systems have been successfully extended to nonparametric bilinear dynamical systems. However, this is not the case for parametric ...
