Function russell_lab::generate2d

pub fn generate2d(
    xmin: f64, 
    xmax: f64, 
    ymin: f64, 
    ymax: f64, 
    nx: usize, 
    ny: usize
) -> (Matrix, Matrix)

Generates 2d points (meshgrid)

Input

• xmin, xmax – range along x
• ymin, ymax – range along y
• nx – is the number of points along x (must be >= 2)
• ny – is the number of points along y (must be >= 2)

Output

• x, y – (ny by nx) matrices

Example

use russell_lab::generate2d;
let (nx, ny) = (5, 3);
let (x, y) = generate2d(-1.0, 1.0, -2.0, 2.0, nx, ny);
assert_eq!(
    format!("{}", x),
