Function orthogonal_init 

pub fn orthogonal_init(
    shape: &[usize],
    gain: f64,
    rng: &mut InitRng,
) -> Result<ArrayD<f64>, InitError>

Orthogonal initialization via QR-like Gram-Schmidt on a random matrix.

Generates a random matrix, then orthogonalises it. For non-square shapes the result is reshaped to the requested dimensions. The gain parameter scales the resulting orthogonal matrix.
