Using MATLAB or GNU octave solved the following problem and provide commentary

I. Use the Around (20*rand (5,5) - 10*ones (5, 5) ) command to generate a random (5 5) matrix A having integer entries selected from [-10, 10]. Use Definition 3 to calculate det (A), using the MATLAB det command to calculate the five cofactors Auu. Au. ., A15. Use matrix surgery to create the five minor matrices Mj (recall that 1I, A12, .. A1s the minor matrix is defined in Definition 2). Compare your result with the value of the determinant of A as calculated by the MATLAB command det (A)
