In any case, I've seen your multidimensional array
implementation
before, and I think it would be a good thing to have it in
Phobos. In
fact, I've written my own as well, and IIRC one or two other
people have
done the same. Clearly, the demand is there.
See also the thread about std.linalg; I think before we can
even talk
about having linear algebra code in Phobos, we need a
solidly-designed
rectangular array API. As I said in that other thread, matrix
algebra
really should be built on top of a solid rectangular array API,
and not
be yet another separate kind of type that's similar to, but
incompatible
with rectangular arrays. A wrapper type can be used to make a
rectangular array behave in the linear algebra sense (i.e.
matrix
product instead of per-element multiplication).
Hi.
I wondered how things were developing with the rectangular arrays
(not sure who is in charge of reviewing, but I guess it is not HS
Teoh). It would be interesting to see this being available for
D, and I agree with others that it is one of the key foundation
blocks one would need to see in place before many other useful
libraries can be built on top.
Let me know if anything I can help with (although cannot promise
to have time, I will try).
Laeeth.
