About

Maintained by Georgi N. BoshnakovFirst published 2017-08-2910 releasesCRAN page ↗GitHub ↗

Provides a class for multi-companion matrices with methods for arithmetic and factorization. A method for generation of multi-companion matrices with prespecified spectral properties is provided, as well as some utilities for periodically correlated and multivariate time series models. See Boshnakov (2002) doi:10.1016/S0024-3795(01)00475-X and Boshnakov & Iqelan (2009) doi:10.1111/j.1467-9892.2009.00617.x.

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

bspm (used by r2u) also needs make: sudo apt install make

zypper -q lr | grep -qi autoCRAN \
