**post** `/api/v1/matrix`

Calculate a distance matrix between points

### Parameters

- `RoutingMatrixParams parameters`

  - `required GeoJsonGeometry destinations`

    Destination points (GeoJSON MultiPoint geometry)

  - `required GeoJsonGeometry origins`

    Origin points (GeoJSON MultiPoint geometry)

  - `Mode mode`

    Travel mode

    - `"auto"Auto`

    - `"foot"Foot`

    - `"bicycle"Bicycle`

### Returns

- `class MatrixResult:`

  - `required IReadOnlyList<IReadOnlyList<Double>> Distances`

    Distance matrix (meters), origins x destinations

  - `required IReadOnlyList<IReadOnlyList<Double>> Durations`

    Duration matrix (seconds), origins x destinations

### Example

```csharp
RoutingMatrixParams parameters = new()
{
    Destinations = new()
    {
        Coordinates = new(

            [
                0
            ]
        ),
        Type = Type.Point,
    },
    Origins = new()
    {
        Coordinates = new(

            [
                0
            ]
        ),
        Type = Type.Point,
    },
};

var matrixResult = await client.Routing.Matrix(parameters);

Console.WriteLine(matrixResult);
```

```json
{
  "distances": [
    [
      0
    ]
  ],
  "durations": [
    [
