PositiveIntegrators.jl: A Julia library of positivity-preserving time integration methods

We introduce PositiveIntegrators.jl, a Julia package that provides efficient implementations of various time integration schemes for the solution of positive ordinary differential equations, making these methods accessible for users and comparable for researchers.Currently, the package provides the unconditionally positivity-preserving MPRK, SSP-MPRK, and MPDeC schemes, which are also conservative when applied to a conservative system.The package is fully compatible with DifferentialEquations.jl, which allows a direct comparison between the provided schemes and standard methods.
