## Cross Product Vectors

**Cross Product Vectors**. The cross product of two vectors a and b is a vector c, length (magnitude) of which numerically equals the area of the parallelogram based on vectors a and b as sides. The dot product ($\vec{a} \cdot \vec{b}$) measures similarity because it.

The function calculates the cross product of corresponding vectors along the first array dimension whose size equals 3. It's useful, but it's much more limited. The dot product is defined in any dimension.
