Module prelude 

Commonly used traits, types, and functions for tensor construction, contraction, and factorization.

use tensor4all_core::prelude::*;

let i = DynIndex::new_dyn(3);
let j = DynIndex::new_dyn(4);
let data: Vec<f64> = (0..12).map(|x| x as f64).collect();
let tensor = IdxTensor::from_dense(vec![i.clone(), j.clone()], data).unwrap();
let result = factorize(&tensor, &[i], &FactorizeOptions::svd()).unwrap();
let recovered = result.left.contract_pair(&result.right).unwrap();
assert!(tensor.distance(&recovered).unwrap() < 1e-12);
