Description: Discretization of the Heat Equation

This benchmark represents a discretized one-dimensional heat equation model. More details can be found in .

For a large-scale heat equation example see the steel profile benchmark.

Origin

This benchmark is part of the SLICOT Benchmark Examples for Model Reduction .

Data

The system matrices $A$, $B$, $C$, $E$ are available from the SLICOT benchmarks page: heat-disc.zip and are stored as MATLAB .mat file.

Dimensions

System structure:

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

System dimensions:

$A \in \mathbb{R}^{200 \times 200}$, $B \in \mathbb{R}^{200 \times 1}$, $C \in \mathbb{R}^{1 \times 200}$, $E \in \mathbb{R}^{200 \times 200}$.
