Re: [Blitz-support] Missing tinyvector product(bzexpr) function

[Julian C. <cum...@ca...>]

Hi Patrik,

Yes, it looks like this is missing but could be added easily.  Compare with
the "dot" function, where there are provided overloads for dotting a
TinyVector with an expression.  Please feel free to submit a patch for this
(or tell me if you need help with that!).

Regards, Julian C.
