Hi,

I'd like to perform a dot/cross product between a Vector3d and a Vector3cd, but the code won't compile. Should I cast Vector3d into Vector3cd? But then I would lose efficiency in addition to casting, since:

1) complex times real = 2 real multiplications
2) complex times complex = 4 real multiplications

Maybe the code doesn't compile due to wrong headers? Or the code isn't implemented (in which case I would be happy to write the corresponding short piece of software, since I really need it).

Any help much appreciated!

indeed currently this is forbidden, though we have all the logic for that. In the meantime for the dot product you can do:

a.adjoint() * b

and for the cross product you'll have to use cast<std::complex<double> >. I'll try to fix it asap.

done for the dot() function.

Thanks! That was a quick one!

done for the cross product too.

btw, the cross product function was not correct for complexes. I also fixed that.

Is it an efficient multiplication, meaning: double times complex? Or is it casting of the doubles to complex, then multiplying?

Oh, and is it ok for Vector3f and Vector3cf as well?

Thanks for the speedy implementation!

there is no conversion, and yes this works for float and any other numeric types.
