torch.mm¶

torch.mm(input, mat2, *, out=None) → Tensor¶

Performs a matrix multiplication of the matrices input and mat2.

If input is a $(n \times m)$ tensor, mat2 is a $(m \times p)$ tensor, out will be a $(n \times p)$ tensor.

Note

This function does not broadcast. For broadcasting matrix products, see torch.matmul().

This operator supports TensorFloat32.

Parameters

• input (Tensor) – the first matrix to be multiplied

• mat2 (Tensor) – the second matrix to be multiplied

Keyword Arguments

out (Tensor, optional) – the output tensor.

Example:

>>> mat1 = torch.randn(2, 3)
>>> mat2 = torch.randn(3, 3)
>>> torch.mm(mat1, mat2)
tensor([[ 0.4851,  0.5037, -0.3633],
        [-0.0760, -3.6705,  2.4784]])
