mul
(input, other, *args, **kwargs)[source]¶ Multiplies each element of the input
input
with the scalarother
and returns a new resulting tensor.Examples:
>>> import torch >>> import treetensor.torch as ttorch >>> ttorch.mul( ... ttorch.tensor([1, 2, 3]), ... ttorch.tensor([3, 5, 11]), ... ) tensor([ 3, 10, 33]) >>> ttorch.mul( ... ttorch.tensor({ ... 'a': [1, 2, 3], ... 'b': {'x': [[3, 5], [9, 12]]}, ... }), ... ttorch.tensor({ ... 'a': [3, 5, 11], ... 'b': {'x': [[31, -15], [13, 23]]}, ... }) ... ) <Tensor 0x7f11b139ca58> ├── a --> tensor([ 3, 10, 33]) └── b --> <Tensor 0x7f11b139cb00> └── x --> tensor([[ 93, -75], [117, 276]])

Description From Torch v1.9.0+cu102¶
-
torch.
mul
(input, other, *, out=None) → Tensor¶ Multiplies
input
byother
.\[\text{out}_i = \text{input}_i \times \text{other}_i\]Supports broadcasting to a common shape, type promotion, and integer, float, and complex inputs.
- Args:
input (Tensor): the input tensor. other (Tensor or Number) - the tensor or number to multiply input by.
- Keyword args:
out (Tensor, optional): the output tensor.
Examples:
>>> a = torch.randn(3) >>> a tensor([ 0.2015, -0.4255, 2.6087]) >>> torch.mul(a, 100) tensor([ 20.1494, -42.5491, 260.8663]) >>> b = torch.randn(4, 1) >>> b tensor([[ 1.1207], [-0.3137], [ 0.0700], [ 0.8378]]) >>> c = torch.randn(1, 4) >>> c tensor([[ 0.5146, 0.1216, -0.5244, 2.2382]]) >>> torch.mul(b, c) tensor([[ 0.5767, 0.1363, -0.5877, 2.5083], [-0.1614, -0.0382, 0.1645, -0.7021], [ 0.0360, 0.0085, -0.0367, 0.1567], [ 0.4312, 0.1019, -0.4394, 1.8753]])
