Description
Maybe this isn't the correct place to ask or maybe I just need a fresh pair of eyes but I'm having trouble using the ndarray-linalg svd function.
the following code throws and error at the unwrap()
X : &ArrayBase<impl Data<Elem = f64>, Ix2>,
) -> Array2<f64> {
let temp:Array2<f64> = X.to_owned().clone();
let (u, s, v) = temp.svd(true, true).unwrap();
while the following does not
x : &ArrayBase<impl Data<Elem = f64>, Ix2>,
n_components : f64,
) -> Self {
let (_n, _m) = x.dim();
//calculate the array of columnar means
let mean = x.mean_axis(Axis(0)).unwrap();
// subtract means from X
let h:Array2<f64> = Array2::ones((_n, _m));
let temp:Array2<f64> = h * &mean;
let b:Array2<f64> = x - &temp;
// compute SVD
let (u, sigma, v) = b.svd(true, true).unwrap();
any help would be appreciated

Research direction
Start by reproducing the failing temp.svd(true, true).unwrap() call and inspect the SVD error rather than relying on unwrap. Compare its input with b.svd(true, true).unwrap(), then determine what input or condition causes the first call to fail and document a reproducible resolution.
