#### static member all: Tensor<bool> -> bool

Checks if all elements of the tensor are true.

##### Declaration

`static member all: src:Tensor<bool> -> bool`

##### Parameters

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

Tensor<bool> | src | The tensor containing the source values. |

##### Returns

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

bool | A scalar containing the result of this operation. |

##### Remarks

It is checked whether all elements of the tensor are true. If so, true is returned; otherwise false is returned.

If the tensor is empty true is returned.

##### Examples

```
let a = HostTensor.ofList2D [[true; true; true]
[false; true; true]]
let b = Tensor.all a // b = false
```
