Argmm

Argmin/max with SIMD support for u8, i32 and f32 arrays and vectors.

Installing

Add the following to your Cargo.toml

argmm = "0.1.1"

Getting started

You can use the extention trait which will take advantage of SIMD if available ```rust use argmm::ArgMinMax;

fn main() { let v = vec![1., 3., -20., 50., -82., 9., -53., 60., 0.]; let minindex = v.argmin(); let maxindex = v.argmax(); asserteq!(minindex, Some(4)); asserteq!(maxindex, Some(7)); } ```

Alternatively, the generic function can be used if you require non-SIMD support for other types

```rust use argmm::generic::{simpleargmin, simpleargmax};

fn main() { let v = vec![1u16, 3, 20, 50, 82, 9, 53, 60, 0]; let minindex = simpleargmin(&v); let maxindex = simpleargmax(&v); asserteq!(minindex, 8); asserteq!(maxindex, 4); } ```

Benchmarks
