These are templates to perform various simple operations on arrays.
Note that the compiler will inline these, so using them carries no performance penalty.

Templated Inner product of two vectors of length 4.
If either x or y has length greater than 4, only the first 4 elements will be used.
x | first reference to the templated class V |
y | second reference to the templated class V |

Templated Inner product of two vectors of length 5.
If either x or y has length greater than 4, only the first 4 elements will be used.
x | first reference to the templated class V |
y | second reference to the templated class V |

inline |
Function that calculates a templated inner product.
This inner product is templated twice. The output variable is hard coded to return a double.
