NLMrs

A Rust crate for building Neutral Landscape Models.

Inspired by nlmpy and nlmr.

Installation

cargo add nlmrs

Example

use nlmrs;

fn main() {
    let arr: Vec<Vec<f64>> = nlmrs::midpoint_displacement(10, 10, 1.);
    println!("{:?}", arr);
}

Export

The export module holds a collection of user-friendly functions to export your 2D NLM vector.

use nlmrs::{distance_gradient, export::write_to_csv};

fn main() {
    let arr: Vec<Vec<f64>> = distance_gradient(50, 50);
    write_to_csv(arr, "./data/data.csv");
}

Visualization

Running script/viz.py will read any contents of data/data.csv and render them as a matplotlib plot.
