Calculates the arithmetic mean of a collection using SIMD instructions. The suffix (x2, x4, x8, x16, x32, x64) indicates the number of lanes processed simultaneously.

Note

: Choose the variant matching your CPU's capabilities. Higher lane counts provide better performance but require newer CPU support.

// Using AVX2 variant (32 lanes at once) - Intel Haswell+ / AMD Excavator+
mean := simd.MeanInt8x32([]int8{1, 2, 3, 4, 5})
// 3

// Using AVX-512 variant (16 lanes at once) - Intel Skylake-X+
mean := simd.MeanFloat32x16([]float32{1.0, 2.0, 3.0, 4.0})
// 2.5

// Using AVX variant (8 lanes at once) - works on all amd64
mean := simd.MeanInt16x8([]int16{10, 20, 30, 40})
// 25

// Empty collection returns 0
mean := simd.MeanUint32x4([]uint32{})
// 0
