Matlab:

Perform row operations: The three elementary row operations can be performed in MATLAB using the following commands

Type I: A $([i,j],$:$)=A([j,i],$:$)$ interchanges row i and row $j$

Type II: A $(i,$:$)=**A(i,$:$)$ multiplies row $i$ by $$

Type III: A $(i,$:$)=A(i,$:$)+**A(j,$:$)$ multiplies row $j$ by $$ and add it to row $i$

Enter the following matrix:

$A=\left[\begin{array}{ccc}3& 5& 4\\ -12& -23& -14\\ 6& 4& 14\end{array}\right]$

Perform row operations in MATLAB that reduce the matrix $A$ to Row Echelon Form. Use format rat.
