Are there any examples of DiscreteProblem usage?

[ChrisRackauckas]

There is a lot of random stuff around. For example

using OrdinaryDiffEqFunctionMap
  function henon_map!(u_next, u, p, t)                                                                                                                                                                              
      u_next[1] = 1 + u[2] - 1.4 * u[1]^2                                                                                                                                                                           
      u_next[2] = 0.3 * u[1]                                                                                                                                                                                        
  end                                                                                                                                                                                                               
  prob = DiscreteProblem(henon_map!, [0.5, 0.5], (0, 100))                                                                                                                                                          
  sol = solve(prob, FunctionMap())

Time-varying parameter specification in DiscreteProblem?

I have a simple DiscreteProblem, based on the SIR epidemic model. I’d like to pass a time-varying parameter to the model, to reduce \beta by a factor v(t). As this is a discrete-time map, I’d like to define v as a vector and just retrieve value at a discrete-time index, as DataInterpolations.jl seems like overkill. Any suggestions on how best to implement this? using OrdinaryDiffEq using Plots @inline function rate_to_proportion(r::Float64,t::Float64) 1-exp(-r*t) end function sir_map!(unp…
