logical_and(x, y)[source]

Element-wise logical AND.

Computes the logical AND for each element \(x_i\) of the input tensor \(x\) with the respective element \(y_i\) of the input tensor \(y\).

Parameters

  • x – first input tensor. Should have a boolean data type.

  • y – second input tensor. Must be compatible with \(x\) (see Broadcasting mechanism and rules ). Should have a boolean data type.

Returns

a tensor containing the result of the element-wise logical AND operation. The returned tensor must have a data type of bool.

Examples

>>> F.logical_and(True, False)
Tensor(False, dtype=bool, device=xpux:0)

Element-wise logical AND:

>>> x = Tensor([True, False, True])
>>> y = Tensor([False, False, True])
>>> F.logical_and(x, y)
Tensor([False False  True], dtype=bool, device=xpux:0)

The & operator can be used as a shorthand for F.logical_and on boolean tensors.

>>> x & y
Tensor([False False  True], dtype=bool, device=xpux:0)
