multiply

→Tensor

multiply(a: Tensor, b: Tensor | Scalar)

Element-wise product.

Verbose alias of the * operator. Broadcasts a and b and applies the standard dtype-promotion rules.

aTensor

First operand.

bTensor | Scalar

Second operand.

Tensor

Element-wise product of the broadcast shape of a and b.

Mathematical definition:

\text{out}_i = a_i \cdot b_i

Gradients: $\partial / \partial a = b$ , $\partial / \partial b = a$ .

>>> import lucid
>>> a = lucid.tensor([1.0, 2.0, 3.0])
>>> lucid.multiply(a, 2.0)
