DifferentialEquations.jl - how to calculate an 'assignment' and pass back to an ODE?

Hi BLI (Bernt?).

Thanks again for your persistence. tspan' in this context is the current time (as you correctly point out - t`).

I have worked on this problem further now and apart from not really understanding how to ‘assign’ the value of a derivative to the expression, i.e. u[3] = 1*floor(tspan/p[6]) I decided to try a different approach.

To that end, I create a function sig(t) that uses nested ifelse. to determine when the input is on or off and then re-use this function inside my perfadap function.

# Function that turns signal on and off
        function sig(t) 
            ifelse.(t<4,0,
                ifelse.(t>=4&&t<5,1,
                    ifelse.(t>=8&&t<9,1,
                        ifelse.(t>=12&&t<13,1,
                            ifelse.(t>=16&&t<17,1,0)
                                            )
                                     )
                              )
                       )
        end

Output :wink:
