Could you please help me to write a cod on MATLAB. Thanks! Q: We need to write 2 files, one will be "Gauss Elimination (GE)" second Upper triangle (ut_sys)" to solve the matrix. The matrix A size will be nxn and the vector d' s size nxn. And we will use "Back Substitution" by solving the matrix. Then we need to use the command window by checking our cod. The example matrix size is 4X4 is okay. I really do not know MATLAB even basic. Could you please explain also. It will be appreciated
