About picking the “gemm” vs “gemv” algorithm automatically for matrix × column:

In a.dot(b)? Anywhere else?

There are two competing concerns with this question:

  • The user knows their data and picks the operation they know they need
  • The library knows the memory layout cases and picks the best algorithm.

    Continuing our conversation in #190, I think I agree with what you said:

    I think it would be natural to have a.dot(b) adaptive but the more raw methods general_mat_mul and general_mat_vec_mul to always use their “gemm” and “gemv” algorithms respectively.

    Essentially, try to be smart but offer an escape hatch for the end user.
