The preferred package is now argminmax which is actively maintained and far more feature complete. This repo will be purely experimental from now on. A special thanks to jvdd for building on the idea and taking it to the next step 👏.
Argmin/max with SIMD support for u8, i16, u16, i32 and f32 arrays and vectors.
Add the following to your Cargo.toml
argmm = "0.1.2"
You can use the extention trait which will take advantage of SIMD if available
use argmm::ArgMinMax;
fn main() {
let v = vec![1., 3., -20., 50., -82., 9., -53., 60., 0.];
let min_index = v.argmin();
let max_index = v.argmax();
assert_eq!(min_index, Some(4));
assert_eq!(max_index, Some(7));
}Alternatively, the generic function can be used if you require non-SIMD support for other types
use argmm::generic::{simple_argmin, simple_argmax};
fn main() {
let v = vec![1u64, 3, 20, 50, 82, 9, 53, 60, 0];
let min_index = simple_argmin(&v);
let max_index = simple_argmax(&v);
assert_eq!(min_index, 8);
assert_eq!(max_index, 4);
