Function variogram_ma_structured 

pub fn variogram_ma_structured(
    f: ArrayView2<'_, f64>,
    mask: ArrayView2<'_, bool>,
    estimator_type: char,
    num_threads: Option<usize>,
) -> Array1<f64>

Variogram estimation of a masked field on a structured grid.

Calculates the empirical variogram according to the equations shown in the module documentation.

Arguments

• f - the spatially distributed data
• mask - the mask for the data f
• estimator_type - the estimator function, can be
  • ‘m’ - Matheron, the standard method of moments by Matheron
  • ‘c’ - Cressie, an estimator more robust to outliers
• num_threads - the number of parallel threads used, if None, use rayon’s default
