I think this is overdone and does not help the intuition. two things: (1). the first step of transposing the second matrix 90 degree is unnecessary and confusing. A row vector and a column vector are different. This step confuses the two. (2). All the final elements are independent and should be calculated in parallel, the stepped anime is not necessary and does not reveal this basic fact. |
