Struct fetish_lib::schmear::Schmear

pub struct Schmear {
    pub mean: Array1<f32>,
    pub covariance: Array2<f32>,
}

Represents a (multivariate) probability distribution by its mean and its covariance. See also InverseSchmear, crate::func_schmear::FuncSchmear

Fields

mean: Array1<f32>

covariance: Array2<f32>

Implementations

impl Schmear

pub fn from_sample_vectors(vecs: &Vec<Array1<f32>>) -> Schmear

Given a collection of points representing samples from some distribution, returns the empirical Schmear describing the sample distribution.

pub fn from_vector(vec: ArrayView1<'_, R32>) -> Schmear

Constructs a Schmear whose mean is the passed vector, and covariance the zero matrix.

pub fn inverse(&self) -> InverseSchmear

Constructs the InverseSchmear which corresponds to this Schmear by taking the pseudoinverse_h of the covariance.

pub fn transform(&self, mat: &Array2<f32>) -> Schmear

Given a matrix representing a coordinate-system transformation, yields this Schmear under the image of the linear transform.

Trait Implementations

impl Clone for Schmear

fn clone(&self) -> Schmear

Returns a copy of the value.

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

Performs copy-assignment from source.
