# coordinate(alongAxis:withShape:name:)

Creates a get-coordindate operation and returns the result tensor.

## Declaration

```swift
func coordinate(alongAxis axis: Int, withShape shape: [NSNumber], name: String?) -> MPSGraphTensor
```

## Parameters

- `axis`: The coordinate axis an element’s value is set to. Negative values wrap around.
- `shape`: The shape of the result tensor.
- `name`: The name for the operation.

## Return Value

Return Value A valid MPSGraphTensor object.

## Discussion

Discussion Creates a tensor of specified shape with value at index [i_0, i_1, ... , i_N] = i_axis For example, coordinateAlongAxis(0, withShape=[5]) = [0, 1, 2, 3, 4]  coordinateAlongAxis(0, withShape=[3,2]) = [[0, 0],                                            [1, 1],                                            [2, 2]]
