MATlab coding project, please help! I tried to figure it out but I'm not sure my code worked out well

Exercise 2 (4 points) **Create the following functions in MATLAB function D-inverses(A) which takes as an input an nn matrix A First, the function has to determine whether A is invertible. (Please use the function rank to do that, the function det is not recommended.) If A is not invertible, the function has to return an empty matrix D=[ ]; and the code terminates with a message "Matrix A is not invertible". If A is invertible, then the function reduces the matrix [A eye(n)] into the reduced echelon form and returns the matrix D that is the inverse of the matrix A. You can use a MATLAB built-in function rref for this part **Type the function inverses in your diary file. *"Run the function D=inverses(A) on the given matrix A in parts (a)-(d) 1-3 2 -4 3 9 -1 5 2 -64-3 -4 12 2 7 (a) A = (c) A-magic(5), 7-5 10 19' 1 23-1 (d) A- magic(4) * *Run a built-in MATLAB function inv on the matrices A for parts (c) and (d) % Write a comment in you diary file why the result obtained by using inv function is inaccurate for the matrix in part (d)
