 axpy_prod(A, x, v, init)implements the well known axpy-product. Setting init totrueis equivalent to callv.clear()beforeaxpy_prod. Currently init defaults totrue, but this may change in the future.Up to now there are some specialisation for compressed matrices that give a large speed up compared to prod. |
