ee.List.sequence
Mantieni tutto organizzato con le raccolte
Salva e classifica i contenuti in base alle tue preferenze.
Genera una sequenza di numeri dall'inizio alla fine (inclusi) con incrementi di passo o con incrementi di conteggio equidistanti. Se la fine non è specificata, viene calcolata da inizio + passo * conteggio, quindi deve essere specificato almeno uno tra fine e conteggio.
| Utilizzo | Resi |

ee.List.sequence(start, end, step, count) | Elenco |
| Argomento | Tipo | Dettagli |
|---|
start | Numero | Il numero iniziale. |
end | Numero, valore predefinito: null | Il numero finale. |
step | Numero, valore predefinito: 1 | L'incremento. |
count | Numero intero, valore predefinito: null | Il numero di incrementi. |
