## 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.
|
||
|
|
||
|
### Notions
|
||
|
|
||
|
[Chapter 7]( https://doc.rust-lang.org/stable/book/ch07-03-paths-for-referring-to-an-item-in-the-module-tree.html )
|
||
|
|
||
|
### Expected Function
|
||
|
|
||
|
```rust
|
||
|
pub fn transpose(m: Matrix) -> Matrix {
|
||
|
}
|
||
|
```
|
||
|
|
||
|
### Usage
|
||
|
|
||
|
Here is a posible program to test your function
|
||
|
|
||
|
```rust
|
||
|
fn main() {
|
||
|
let matrix = Matrix((1, 3), (4, 5));
|
||
|
println!("Original matrix {:?}", matrix);
|
||
|
println!("Transpose matrix {:?}", transpose(matrix));
|
||
|
}
|
||
|
```
|
||
|
|
||
|
And it's output:
|
||
|
|
||
|
```console
|
||
|
student@ubuntu:~/[[ROOT]]/test$ cargo run
|
||
|
Original matrix Matrix((1, 3), (4, 5))
|
||
|
Transpose matrix Matrix((1, 4), (3, 5))
|
||
|
student@ubuntu:~/[[ROOT]]/test$
|
||
|
```
