%description
A 'greta' extension for analysing transition matrices and ordinary
differential equations representing dynamical systems. Provides functions
for analysing transition matrices by iteration, and solving ordinary
differential equations. This is an extension to the 'greta' software,
Golding (2019) <doi:10.21105/joss.01601>.
