Function linfa_reduction::utils::to_gaussian_similarity

pub fn to_gaussian_similarity(
    observations: &ArrayBase<impl Data<Elem = f64>, Ix2>, 
    eps: f64
) -> Array2<f64>

Computes a similarity matrix with gaussian kernel and scaling parameter eps

The generated matrix is a upper triangular matrix with dimension NxN (number of observations) and contains the similarity between all permutations of observations similarity
