The added method `Vector::axcpy` generalises `Vector::gemv` to noncommutative cases since it allows us to write for `gemv` `self.axcpy(alpha, &col2, val, beta)`, instead the usual `self.axpy(alpha * val, &col2, beta)`. Hence, `axcpy` preserves the order of scalar multiplication which is important for applications where commutativity is not guaranteed (e.g., matrices of quaternions, etc.). This commmit also removes helpers `array_axpy` and `array_ax`, and replaces them with `array_axcpy` and `array_axc` respectively, which like above preserve the order of scalar multiplication. Finally, `Vector::axpy` is preserved, however, now expressed in terms of `Vector::axcpy` like so: ``` self.axcpy(alpha * val, &col2, beta) ``` |
