But just to clarify: Dot is really very different from Times because conventional matrix multiplication is not commutative, whereas Times doesn't care about the order of the factors. BTW - …

WitrynaIn quantum-mechanical matrix notation, the inner product and the action of operators on state vectors are implemented as matrix multiplication. The standard Dot product in Mathematica does not properly handle the inner product of vectors whose components are operators, because it tries to contract the last index of the first argument with the … WitrynaTwo matrices can only be multiplied if the number of columns of the matrix on the left is the same as the number of rows of the matrix on the right. For example, the following multiplication cannot be performed because the first matrix has 3 columns and the second matrix has 2 rows: However, if we reverse the order, they can be multiplied.
