You can enter the coefficients of a given characteristic equation to check the stability of the system.
This program addresses the cases of zero elements in the first column and zero rows.
The problem of zero element in the first column is solved by adding two more poles to the LHP. ( [old polynomial * (s^2+ n*s + m) ] this does not affect the result.) Some programs use 'eps'; it is not convenient in polynomials of higher orders.

Please let me know if there are any problems.
