Over the last two decades several approaches have been suggested to numerically preserve the positivity of positive ordinary differential equation (ODE) systems. This Julia package provides efficient implementations of various positive time integration schemes, allowing a fair comparison of the different schemes. The package extends OrdinaryDiffEq.jl by
