Hi @Wu-Chenyang , Thank you for the PR! I am a bit confused though - why does this speed things up? I thought that += and .+= do the same thing for vectors and * and .* do the same thing for a scalar multiplied by a vector. Did you observe a substantial speed-up? |

The reason is explained here. I've also examined its effectiveness through ProfileView. |

Ok, thanks @Wu-Chenyang ! |
