+MATLABDiffEq.jl is simply a solver on the DiffEq common interface, so for details see the [DifferentialEquations.jl documentation](https://juliadiffeq.github.io/DiffEqDocs.jl/dev/). However, there are three things to know:
 
 1. The only options implemented are those for error calculations (`timeseries_error`), `saveat` and tolerances.
 2. The input function must be defined by a `ParameterizedFunction`
