How to check whether a matrix is a square matrix in Rust

Answer 1

fn is_square_matrix<T>(matrix: &[Vec<T>]) -> bool {
    let len = matrix.len();
    
    matrix.iter().all(|row| row.len() == len)
}

fn main() {
    let matrix = vec![
        vec![1, 2, 3],
        vec![4, 5, 6],
        vec![7, 8, 9],
    ];

    if is_square_matrix(&matrix) {
        println!("The matrix is a square matrix.");
    } else {
        println!("The matrix is not a square matrix.");
    }
}



/*
run:

The matrix is a square matrix.
