Struct Histogram 

pub struct Histogram {
    pub bins: Vec<u64>,
    pub lo: f64,
    pub hi: f64,
}

Fixed-bin histogram over a f64 slice.

Values outside [lo, hi) are clamped into the boundary bins. Mimics a GPU atomic histogram with one thread per element.

Fields

bins: Vec<u64>

Bin counts.

lo: f64

Lower bound of the first bin.

hi: f64

Upper bound of the last bin (exclusive).

Implementations

impl Histogram

pub fn compute(data: &[f64], lo: f64, hi: f64, n_bins: usize) -> Self

Compute a histogram with n_bins bins over [lo, hi).

Panics if n_bins == 0 or lo >= hi.

pub fn total(&self) -> u64

Total count of elements in all bins.

pub fn bin_centre(&self, i: usize) -> f64

Centre value of bin i.

pub fn mode_bin(&self) -> usize

Index of the most-populated bin (mode).

pub fn approx_mean(&self) -> f64

Approximate mean computed from bin centres.

Trait Implementations

impl Clone for Histogram

fn clone(&self) -> Histogram

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Histogram

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
