Function solve_2x2 

pub fn solve_2x2(matrix: Matrix2, rhs: Vector2) -> Result<Vector2, LinearError>

Solves matrix * x = rhs for x.

Errors

Returns LinearError::SingularMatrix when the determinant is zero or non-finite.

Examples

use use_linear::solve_2x2;
use use_matrix::Matrix2;
use use_vector::Vector2;

let matrix = Matrix2::new(2.0, 1.0, 5.0, 3.0);
let rhs = Vector2::new(1.0, 2.0);

assert_eq!(solve_2x2(matrix, rhs)?, Vector2::new(1.0, -1.0));
