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