Matrix*Vector and Vector*Matrix

[Holgerson]

Hi everybody,

I wonder if someone knows how to implement an operator* into NRVec and/
or NRMat, respectively, that can perform these kind of operations:
Matrix*Vector and Vector*Matrix. Thanks a lot,

Holger

See my reply to your other question for answers on that one. Please
notice though that these kinds of operations are usually undesirable
since they do not perform so well.

Hi,

I think you'd better try the blitz array library from
http://www.oonumerics.org/blitz/ and modify the NR algorithms to work
with it.
It has pretty much everything you need and it's very efficient (uses
expression templates).

Dear Valeriu,

I did load that blitz-tool down and it looks very promising to me, so
I may want to use it. Thanks a lot,
