Matrix Multiplication for 1D

[sociopath00]

In the course, we have tensor = torch.tensor([1,2,3]) which has 1D only. In this case how matrix multiplication works. As per the rules it should have same inner dimensions. When we do torch.matmul(tensor, tensor) how the 2 rules of matrix multiplications are applied here?

I believe that behind the scenes torch just returns the dot product of the two vectors
