what is the transpose of a matrix

The transpose of a matrix is just a flipped version of 
the original matrix. We can transpose a matrix by switching 
its rows with its columns. The original rows become the new columns
and the original columns become the new rows.
We denote the transpose of matrix A by AT. 

For example:
	1 2 3                      1 4 7
A = 4 5 6       then      AT = 2 5 8
    7 8 9                      3 6 9
    
Similarly if 

B = 1 2 3       then      BT = 1 4
    4 5 6                      2 5 
                               3 6

Transpose a matrix

// Transpose a matrix
fn matrix_transpose(m: Vec<Vec<i32>>) -> Vec<Vec<i32>> {
    let mut t = vec![Vec::with_capacity(m.len()); m[0].len()];
    for r in m {
        for i in 0..r.len() {
            t[i].push(r[i]);
        }
    }
    t
}

fn main() {
    let m = vec![vec![1, 2, 3], vec![4, 5, 6], vec![7, 8, 9]];
    println!("Matrix:
{:?}", m);
    let t = matrix_transpose(m);
    println!("Transpose:
{:?}", t);
}
