inline

Scalar product of two dense tensors.

By default, the values of the second tensor are complex-conjugated. Legs of the tensors have to be in the same order, i.e. the n-th leg of the first tensor is contracted with the n-th leg of the second tensor. Equivalent to reshaping both tensors into vectors and taking the Euclidean scalar product of those.
