Origin

This benchmark is part of the Oberwolfach Benchmark Collection^[1]; No. 38866, see also ^[2].

Data

The matrices are in Matrix Market format inlet.tar.gz. The size of the file is 5.4 MB. The matrix name is used as an extension of the matrix file.

Dimensions

System structure:

\begin{align} E \dot{x}(t) &= Ax(t) + Bu(t) \\ y(t) &= Cx(t) \end{align}

System dimensions:

$E \in \mathbb{R}^{11730 \times 11730}$ , $A \in \mathbb{R}^{11730 \times 11730}$ , $B \in \mathbb{R}^{11730 \times 2}$ , $C \in \mathbb{R}^{1 \times 11730}$
