Detailed Description

template<SimdPolicy Policy = default_simd_policy>
class kcenon::container::simd::simd_ops< Policy >

SIMD operations wrapper with compile-time policy selection.

Template Parameters

Policy

SIMD policy class (must satisfy SimdPolicy concept)

Usage:

// Use default (best) policy for platform
simd_ops<> ops;
 
// Use explicit scalar policy for testing
simd_ops<scalar_simd_policy> scalar_ops;
