Re: [Blitz-support] matrix-vector multiplication

[Patrik J. <co...@fa...>]

If you use 1D Arrays instead of Vectors, it should work.

Also, since you are using Vector, this seems to indicate you are using
version 0.9. That version is very old, so I'd encourage you to check
out the most recent version from the Mercurial repository.

cheers,
