I need help to solve this MATLAB question.

2) In a first course in linear algebra you probably learned how to compute inverses using row operations. Start with the square matrix A (say nxn) augment by the nxn identity matrix, [A] 1) and row reduce to the form [1 | B]. Then B is the inverse of A. Using the matrix A from the previous problem, do this using MATLAB's commands for building up matrices and extracting parts. The command rref gives the reduced row echelon form
