matrix_transposition

Instructions

• Define the structure matrix as a tuple of tuples of i32's

• Define a function that calculate the transpose matrix of a 2x2 matrix.

• Note:

  • The transpose of a matrix A is the matrix A' where A''s columns are A's row and the rows are the columns:

Example:

( a b )   __ transposition __>   ( a d )
( c d )                          ( b d )

• Matrix must implement Debug, PartialEq and Eq. You can use derive

• Remember that you're defining a library so you have to make public the elements that are going to be called from an external crate.

Expected Function

pub fn transpose(m: Matrix) -> Matrix {
}

Usage

Here is a posible program to test your function

fn main() {
    let matrix = Matrix((1, 3), (4, 5));
    println!("Original matrix {:?}", matrix);
    println!("Transpose matrix {:?}", transpose(matrix));
}

And it's output:

student@ubuntu:~/[[ROOT]]/test$ cargo run
Original matrix Matrix((1, 3), (4, 5))
Transpose matrix Matrix((1, 4), (3, 5))
