Functions

func DotProduct

func DotProduct(left, right []float32, result *float32)

DotProduct calculates the dot product of two vectors using NEON or AVX SIMD instructions if supported, otherwise it falls back to the standard implementation.

Parameters:

• left: the first vector
• right: the second vector
• result: the initial value of the result

Returns:

• the dot product of the two vectors

func Supported

func Supported() bool
