Re: [Python-ideas] Fwd: [RFC] draft PEP: Dedicated infix operators for matrix multiplication and matrix power

Matrix multiplication is only defined on 2d arrays (matrices). But why not on arbitrary tensors (except scalars)?

The PEP does include a (complicated) definition of "matrix multiplication" for arrays of all ranks. In particular, @-multiplication of rank-1 arrays is the dot product.
