# Scenario/get_subscenario

> Get subscenario from a `Scenario` instance

---

## Description
Get subscenario of `scenario` over time slots `ini`, `ini`+1, $\dots$ , `fin`-1.

- If `future_evs == true`, the subscenario is composed of the EVs satisfying `Arr_time < fin` and `Dep_time > ini`, i.e., the EVs connected to chargers at some time slot among `ini`, `ini`+1, $\dots$ , `fin`-1.
- If `future_evs == false`, the subscenario is composed of the EVs satisfying `ARr_time <= ini` and `Dep_time < ini`, i.e., the EVs connected to chargers at time slot `ini`.
- If the name-value argument `E_ini` is provided, then for each `i`, `EVs(i).E_ini` is set to `E_ini(i)`.
- The output `ev_ind` is a row vector containing the indices of EVs in `scenario` that form the subscenario.
