square(x)[source]#

Element-wise \(x^2\) function.

Calculates the square for each element \(x_i\) of the input tensor \(x\).

Parameters:

x (Tensor) – input tensor. Should have a floating-point data type.

Return type:

Tensor

Returns:

a tensor containing the evaluated square root result for each element in \(x\). The returned tensor must have a floating-point data type determined by Type promotion rules.

Examples

>>> F.square(2)
Tensor(4, dtype=int32, device=xpux:0)

Element-wise square:

>>> x = Tensor([1, -2, -3, 4])
>>> F.square(x)
Tensor([ 1  4  9 16], dtype=int32, device=xpux:0)
