New Post: how to do a cross product?

There is a reason there is no cross product available in the Math.NET Numerics linear algebra vectors: the cross product doesn't make a lot of sense in the context of linear algebra, and is even defined for vectors of length 3 only.

However, there is a related project called Math.NET Spatial which is designed for spatial geometry and, of course, does provide the fundamental cross product on its Vector3D type.

Thanks,
