Struct psyche_utils::grid::GridSamplerCluster

pub struct GridSamplerCluster {
    pub from: (usize, usize),
    pub to: (usize, usize),
}

Grid sampler that sum fields contained by cluster bounds.

Note

Weight component of sampling result equals number of sampled fields.

Example

use psyche_utils::grid::{Grid, GridSamplerCluster};

let grid = Grid::new(2, 2, 1.0);
let sampler = GridSamplerCluster::new((0, 0), (1, 1));
assert_eq!(grid.sample(sampler).unwrap(), (4.0, 4));

Fields

from: (usize, usize)

Bounds column and row starting point.

to: (usize, usize)

Bounds number of columns and rows that defines cluster size.
