ndarray-rand #530
Description
The random function from the ndarray_rand::RandomExt trait seems to go unrecognized when following the test example on the repo.
extern crate rand;
extern crate ndarray;
extern crate ndarray_rand;
#[cfg(test)]
mod tests {
use rand::distributions::Range;
use ndarray::Array;
use ndarray_rand::RandomExt;
#[test]
fn it_works() {
assert_eq!(2 + 2, 4);
let (mm, nn) = (5, 5);
for m in 0..mm {
for n in 0..nn {
let a = Array::random((m, n), Range::new(0., 2.));
assert_eq!(a.shape(), &[m, n]);
assert!(a.iter().all(|x| *x <= 2.));
assert!(a.iter().all(|x| *x >= 0.));
}
}
}
}
