PyTorch element-wise product of vectors / matrices / tensors

Question

In PyTorch, how do I get the element-wise product of two vectors / matrices / tensors?

For googlers, this is product is also known as:

• Hadamard product
• Schur product
• Entrywise product

Answer 1

Given two tensors A and B you can use either:

• A * B
• torch.mul(A, B)
• A.mul(B)

Note: for matrix multiplication, you want to use A @ B which is equivalent to torch.matmul().
