ee.List.sequence
Stay organized with collections
Save and categorize content based on your preferences.
Generate a sequence of numbers from start to end (inclusive) in increments of step, or in count equally-spaced increments. If end is not specified it is computed from start + step * count, so at least one of end or count must be specified.
| Usage | Returns | ee.List.sequence(start, end, step, count) | List |
| Argument | Type | Details | start | Number | The starting number. |
end | Number, default: null | The ending number. |
step | Number, default: 1 | The increment. |
count | Integer, default: null | The number of increments. |
Examples
Code Editor (JavaScript)
print(ee.List.sequence(0, 5)); // [0,1,2,3,4,5]
print(ee.List.sequence(0, 10, 2)); // [0,2,4,6,8,10]
print(ee.List.sequence(0, null, 2, 6)); // [0,2,4,6,8,10]
print(ee.List.sequence(0, null, -2, 6)); // [0,-2,-4,-6,-8,-10]
// Step ignored when present along with count.
print(ee.List.sequence(0, 10, 2, 999)); // 999 elements
print(ee.List.sequence(0, 10, 2, 3)); // [0,5,10]
// Using a dictionary for arguments.
print(ee.List.sequence({start:10, count:3})); // [10,11,12]
print(ee.List.sequence({start:3, step:2, end:6})); // [3,5]
// [-1000000000,0,1000000000]
print(ee.List.sequence({start:-1e9, end:1e9, count:3}));
