Fitting results of delayed differential equations in monolix are not reproducible using the dde23 function in Matlab

[Angieraad15]

Hi,

I have a small enquiry regarding the delayed differential equations in monolix as it seems plots are not reproducible using the dde23 function in Matlab .
I have estimated model parameters using a delayed differential equation in monolix (using an extended SEIR epidemiological model). Now when plotting the model using the estimated parameters from monolix while overlaying the data points, I do not get the same fitting plots as
monolix.
I have looked at both solvers and it seems that both use the Runge-kutta method so not sure why I am getting those significantly different results.

Any advice would be much appreciated !

Thanks
