computes
axpy_prod(A, x, v, init) implements the well known axpy-product. Setting init to true is equivalent to call v.clear() before axpy_prod . Currently init defaults to true , 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. |
