Preliminary notes:

  • Abstract is left out of the type names for conciseness
  • We need a Covector (or alternative name) type for theoretical reasons, i.e. to make dispatch able to distinguish between all of the following operations and to have methods with a different return type for these different operations.
  • We need a LazyTranspose type (and Covector) for computational efficiency, i.e. to link with BLAS, to replace the current Ac_mul_Bt etc family.
  • Alternatives with ? ... ? are not very likely, just to point out the possibility.

Given vectors v and w, linear maps with matrix representation A and B, and a covector z
