Programming Assignment: Eigenvalues and Eigenvectors grading issue

I have submitted the last programming assignment : Eigenvalues and Eigen Vectors with all tests passed but in the grading i got 0, because i might have changed the some code lines and i have declared A_eig myself that is showing in the feedback of every grading exercise that A_eig is not defined how i can resolve the issue if anyone have the original code for this lab without imputing the required solution kindly give me that code so that i can start from scratch or there is any other solution for it
