outer¶

paddle. outer ( x, y, name=None ) [source]

Outer product of two Tensors.

Input is flattened if not already 1-dimensional.

Parameters

• x (Tensor) – An N-D Tensor or a Scalar Tensor.

• y (Tensor) – An N-D Tensor or a Scalar Tensor.

• name (str, optional) – Name for the operation (optional, default is None). For more information, please refer to Name.

Returns

The outer-product Tensor.

Return type

Tensor

Examples

import paddle
x = paddle.arange(1, 4).astype('float32')
y = paddle.arange(1, 6).astype('float32')
out = paddle.outer(x, y)
print(out)
#        ([[1, 2, 3, 4, 5],
#         [2, 4, 6, 8, 10],
#         [3, 6, 9, 12, 15]])
