I didn't mean to have laplacian be part of get.adjacency as it is a conceptual/naming conflict, I don't know why I thought to add it there quite frankly!?! :)  it makes perfect sense to have it as a standalone igraph_laplacian

I'm attaching the function. the directed case can certainly be removed if deemed unnecessary.

thanks again for all your help, igraph is really great!

No, not at all. :) Your patch was quite carefull, you even updated the
manual page, etc. So, again, if you need a C version, i'm happy to include
it in the library, but please write it as a separate function.
If you don't need it i might write it ... sometime in the future.

Thanks again,
