Function Documentation

__attribute__

(

(always_inline)

)

Inlined function to compute the distance^2 between two vectors.

Parameters:

x1	The first vector.
x2	The second vector.
dx	An array in which x1 - x2 will be stored.

Returns:

The Euclidian distance squared between x1 and x2.

Depending on the processor features, this function will use SSE registers and horizontal adds.
