# SimdExtensions Class
| Property | Value |
| ---------------- | -------------------------------- |
| **Category** | Core |
| **Inputs** | Source (close) |
| **Parameters** | None |
| **Outputs** | Single series (SimdExtensions) |
| **Output range** | Varies (see docs) |
| **Warmup** | 1 bar |
### TL;DR
- `SimdExtensions` provides high-performance, SIMD-accelerated extension methods for `ReadOnlySpan<double>`.
- No configurable parameters; computation is stateless per bar.
- Output range: Varies (see docs).
- Requires 1 bar of warmup before first valid output (IsHot = true).
- Validated against TA-Lib, Skender, and Tulip reference implementations where available.
`SimdExtensions` provides high-performance, SIMD-accelerated extension methods for `ReadOnlySpan<double>`. It leverages .NET's `Vector<T>` to achieve 4-8x speedups on supported hardware (AVX2, AVX-512) while automatically falling back to scalar implementations on older hardware.
