A linear homogeneous ordinary differential equation with constant coefficients has the general form of
where are all constants.with constant coefficients has the general form of where are all *constants*. so the spad function need to check all the a i's are constant and return true and otherwise false. i will check the operations available in fricas. Actually I have 7 exams in next 4 days so not able to code properly but as soon as it ends I will be fully devoted.
