WebTensors are simply mathematical objects that can be used to describe physical properties, just like scalars and vectors. In fact tensors are merely a generalisation of scalars and vectors; a scalar is a zero rank tensor, and a vector is a first rank tensor. The rank (or order) of a tensor is defined by the number of directions (and hence the ... Webtorch.matmul(input, other, *, out=None) → Tensor. Matrix product of two tensors. The behavior depends on the dimensionality of the tensors as follows: If both tensors are 1-dimensional, the dot product (scalar) is returned.

"WebThe vast majority of engineering tensors are symmetric. One common quantity that is not symmetric, and not referred to as a tensor, is a rotation matrix. Tensors are in fact any physical quantity that can be represented by a scalar, vector, or matrix. Zero-order tensors, like mass, are called scalars, while 1st order tensors are called vectors.
