# Method productAxis

#### static member productAxis: int -> Tensor<'T> -> Tensor<'T>

Calculates the product of the elements along the specified axis.

##### Declaration

`static member productAxis: ax:int -> src:Tensor<'T> -> Tensor<'T>`

##### Parameters

Type | Name | Description |
---|---|---|

int | ax | The axis to calculate the product along. |

Tensor<'T> | src | The tensor containing the source values. |

##### Returns

Type | Description |
---|---|

Tensor<'T> | A new tensor containing the result of this operation. |

##### Remarks

The product is calculated along the specified axis. An empty product equals one.

##### Examples

```
let a = HostTensor.ofList2D [[1.0; 2.0; 3.0; 4.0]
[5.0; 6.0; 7.0; 8.0]]
let b = Tensor.productAxis 1 a // b = [24.0; 1680.0]
```
