Question: Use elementary row operation to determine the reduced row echelon form of the following matrices. Show work by hand and check your answer using MATLAB's

Use elementary row operation to determine the reduced row echelon form of the following matrices. Show work by hand and check your answer using MATLAB's rref command (2pt each). [1 2 3 2 5 6 3 4 8] [1 1 2 2 1 1 1 0 - 1] Find the value of the determinant only. Show hand calculation and check answer with MATLAB (2pt each). [2 - 1 1 1 3 2 3 2 3] [1 1 1 - 1 1 - 1 - 1 1 2 1 - 1 2 3 1 2 - 1]
