16 | // As a matrix multiplication library, Ruy offers a Mul entry point, performing |
17 | // matrix multiplication. For implementation purposes, it is much nicer to |
18 | // be dealing with the transpose-and-multiply operation, doing |
19 | // Destination = Transpose(LHS) * RHS |
20 | // Indeed, the latter is performing dot-products between the *columns* of LHS |
21 | // and the columns of RHS, whereas a plain matrix multiplication is performing |
22 | // dot-products between the *rows* of LHS and the columns of RHS. |
23 | // That is why TrMul is nicer to implement, allowing for a more symmetric |
24 | // treatment of LHS and RHS. |
