[FEAT] Matrix: transpose and inverse functions

[KjetilIN]

🚀 Feature

Description

Implement the transpose and inverse functions for a matrix:

    /// Not implemented
    pub fn transpose(&mut self){
        unimplemented!()
    }

    /// Not implemented
    pub fn get_transposed(&self) -> Matrix{
        unimplemented!()
    }

    /// Not implemented
    pub fn inverse(&mut self){
        unimplemented!()
    }

    /// Not implemented
    pub fn get_inverse(&self)-> Matrix{
        unimplemented!()
    }
