Well, as the discussion on the list shows, there is some demand for a
library like this. Unfortunately, the X10 core team currently does not
have the resources to work on the implementation of a matrix library.
However, X10 is an open-source project, and we would be happy to get
more participation and contributions from the community. We have
already integrated some of the missing functionality in the Math
library implemented by Josh Milthorpe.
So if you wish to spend some time on this and propose an API, we will
definitely discuss it in the core team. The best mechanism for such
a proposal is to actually write the X10 code and attach it to a JIRA
issue (which will let us track it and comment on it in a publicly
accessible forum). Also note that there's no need to actually provide
the full implementation right away -- X10 supports an "incomplete"
method attribute for exactly that purpose. The actual implementation
could be filled in later.
Let me know if you plan to work on this and are interested in more
details.
