================================

[](#widi-nearestneighbor-feature-set)

Sample of usage
---------------

[](#sample-of-usage)

```
use Widi\NearestNeighbor\Vector;
use Widi\NearestNeighbor\Factory\VectorFactory;

$vectorATwoDimensions = new Vector(11,2);
$vectorBTwoDimensions = new Vector(4,5);
$vectorAThreeDimensions = new Vector(1,5,10);

// this will return true
$vectorATwoDimensions->isCompatible($vectorBTwoDimensions);
// this will return false
$vectorATwoDimensions->isCompatible($vectorThreeDimensions);

// returns 2
$vectorATwoDimensions->getDimensionCount();
// returns 3
$vectorAThreeDimensions->getDimensionCount();

// this should return 7.615773
$vectorATwoDimensions->calculateDistanceTo($vectorBTwoDimensions);

// with factory
$factory = new VectorFactory();
$vector = $factory->create(1,2,3);

// find nearest neighbor
$vectorA = new Vector(0,0);
$vectorB = new Vector(1,1);
$vectorC = new Vector(2,2);

$collection = new VectorCollection(
    $vectorA,
    $vectorB,
    $vectorC
);

// this will return the instance of $vectorA
$collection->findClosest(new Vector(0.1,0.1));
