This crate provides a struct representing a multidimensionnal array together with a Unit.
It allows to do computations taking into account the unit of your n-dimensional array.
```rust use ndarray_unit::*;
extern crate ndarray; use ndarray::Array;
fn main() { println!("meter / second = {}", &getmeter() / &getsecond());
let arr1 = Array::linspace(30.0, 40.0, 11);
let arr_u1 = ArrayUnit::new(arr1, get_joule());
let arr2 = Array::linspace(10.0, 60.0, 11);
let arr_u2 = ArrayUnit::new(arr2, get_second());
let arr3 = ndarray::array![
[1.0, 0.0, 2.0, 6.0],
[1.0, 2.0, 3.0, 5.0],
[1.0, 2.0, 3.0, 6.0]
];
let arr_u3 = ArrayUnit::new(arr3, get_meter());
println!("arr_u3 = {}", arr_u3);
println!("==========================================================");
println!("{}\n*{}\n={}", &arr_u1, &arr_u2, &arr_u1 * &arr_u2);
println!("==========================================================");
println!("{}\n/{}\n={}", &arr_u1, &arr_u2, &arr_u1 / &arr_u2);
println!("==========================================================");
println!("{}\n+{}\n={}", &arr_u1, &arr_u1, &arr_u1 + &arr_u1);
println!("==========================================================");
println!("{}\n-{}\n={}", &arr_u2, &arr_u2, &arr_u2 - &arr_u2);
println!("==========================================================");
}

The program will panic when you try to add or substract two ArrayUnits with different Units.
```rust
extern crate ndarray;
use ndarray::Array;
use ndarray_unit::*;
let arr1 = Array::linspace(30.0, 40.0, 11); let arru1 = ArrayUnit::new(arr1, getjoule());
let arr2 = Array::linspace(10.0, 60.0, 11); let arru2 = ArrayUnit::new(arr2, getsecond());
// let result = &arru1 + &arru2; // ==> panicking ```
