Usage

To bring this crate into scope, either add reduced_row_echelon_form_jeck@0.1.0 to your dependencies in cargo.toml, or run cargo add reduced_row_echelon_form_jeck@0.1.0.

Here is an example that creates a new Rust project, adds reduced_row_echelon_form_jeck , and shows how to use the api to convert a Matrix to RREF.

First, create a new directory and create a new cargo instance:

$ mkdir reduced_row_echelon_form_jeck_example
$ cd reduced_row_echelon_form_jeck_example
$ cargo init

Second, add reduced_row_echelon_form_jeck to dependancies

$ cargo add reduced_row_echelon_form_jeck

Then, go to src/main.txt. Replace the contents with:

fn main() {
    use reduced_row_echelon_form_jeck::Matrix;
    // Matrices are vectors of Rows
    let matrix = vec![
        vec![1.0, 3.0],
        vec![2.0, 1.5],
        vec![-2.0, -1.5],
    ];
    let matrix = Matrix::from(matrix).to_reduced_row_echelon_form();
    
    let matrix_in_form = vec![
        vec![1.0, 0.0],
        vec![0.0, 1.0],
        vec![0.0, 0.0],
    ];
    assert_eq!(matrix.matrix, matrix_in_form);
    println!("{}", matrix);
}

Finally, run the program with cargo run The output should be, Note: subsequent runs might look a little different:

$ cargo run
