Kronecker product property
Web6 mrt. 2024 · Today, let’s play with Kronecker products in SymPy, which is a method to create matrices out of blocks of smaller matrices. The classical example for me are the Dirac gamma matrices, so let’s ... Web6 okt. 2024 · The tensor product of objects with k and ℓ indices should naturally have k + ℓ indices. The vector outer product combines two 1-index vectors into a 2-index matrix, but the Kronecker product has to encode its 2+2 input indices into 2 output indices because matrices only support two indices.
