torch.mm(mat1, mat2) performs a matrix multiplication of mat1 and mat2
a = torch.randint(0, 5, (2, 3)) # tensor([[3, 3, 2],
# [2, 2, 2]])
b = torch.randint(0, 6, (3, 1)) # tensor([[1],
# [4],
# [5]])
torch.mm(a, b) # tensor([[11],
# [17]])
torch.mul(input, other) multiplies each element of the 'input' with the scalar in 'other' and returns a new resulting tensor.
a = torch.tensor([[1, 2, 3],
[4, 5, 6]])
b = torch.tensor([1, 2, 3])
c = torch.tensor([[1],
[2],
[3]])
torch.mul(a, 10) # tensor([[10, 20, 30],
# [40, 50, 60]])
torch.mul(a, b) # tensor([[ 1, 4, 9],
# [ 4, 10, 18]])
torch.mul(b, c) # tensor([[1, 2, 3],
# [2, 4, 6],
# [3, 6, 9]])
