# dedup
|
|
|
|
Eliminating duplicate copies of repeating vectors.
|
|
|
|
**Since:** 2.3
|
|
|
|
## Parameters
|
|
|
|
- `lt` : A list of vectors.
|
|
- `eq` : A equality function. If it's ignored, use `==` to compare elements. **Since: ** 3.0
|
|
- `hash` : A hash function. If it's ignored, convert each element to a string and hash it. **Since: ** 3.0
|
|
- `number_of_buckets` : The function uses a hash table internally. Change the number of buckets if you're trying to do optimization. **Since: ** 3.0
|
|
|
|
## Examples
|
|
|
|
eq = function(e1, e2) e1[0] == e2[0] && e1[1] == e2[1] && e1[2] == e2[2];
|
|
|
|
points = [[1, 1, 2], [3, 4, 2], [7, 2, 2], [3, 4, 2], [1, 2, 3]];
|
|
assert(
|
|
dedup([[1, 1, 2], [3, 4, 2], [7, 2, 2], [3, 4, 2], [1, 2, 3]])
|
|
== [[1, 1, 2], [3, 4, 2], [7, 2, 2], [1, 2, 3]]
|
|
);
|
|
|
|
assert(
|
|
dedup([[1, 1, 2], [3, 4, 2], [7, 2, 2], [3, 4, 2], [1, 2, 3]], eq = eq)
|
|
== [[1, 1, 2], [3, 4, 2], [7, 2, 2], [1, 2, 3]]
