I have an ODE system from OrdinaryDiffEq.jl. I want to model a digital filter that needs to know the past 7 values of a particular variable. Essentially, I want a buffer of sorts to keep track of the value of this variable through previous iterations of the solver. Currently, I have implemented a sort of sliding window in the canonical variables u where I manually shift over the current values in the array to the left and add the new value at the end.
for i in 1:6 u[i - 1] = u[i] end u = value
Is there anything built into to DifferentialEquations.jl or Julia that handles this kind of functionality that I’m looking for? Any advice or suggestions is much appreciated.
