With other solvers that implement adaptive step size you can not know in advance at what t the ODE model function is called. You should implement U via some kind of interpolation function, in …
Nettet16. feb. 2024 · Introduction. State space models (SSM) are latent variable models which are commonly applied in analysing time series data due to their flexible and general framework (cf.
