Inclusion of AB13HD method for L-infinity norm computation of Descriptor Systems #5

Closed Algopaul closed 2 years ago

Algopaul commented 2 years ago

The function AB13HD (available, e.g., here) written by @VasileSima4 and Matthias Voigt is currently not included in this repository. However, AB13HD is needed for computing the L-infinity norm, when the E matrix (in an EABCD-system) is singular. The function AB13DD, that is currently available, assumes that E is nonsingular. Is it possible to include AB13HD into the SLICOT-Reference repository? In this way it would also be automatically available e.g. to julia users via SLICOT_jll. Can we just open a pull-request with the code from this link or is further testing/documentation needed?

I will do some further testing of AB13HD in the next few weeks, and then add it to the SLICOT-Reference repository.
