Sorry... so many typos...1. MX Should be KX
2. Substitute X with L, we get a group of linear inequations for t only. (Should be ln(t) = ln1 t + ln2). t is an real variable.
3. Mn(t) will be some function regarding to t but no longer polynomial or linear, like exp(t) + 2sin(t), or t^5 + ln(t)....
i'm still confused
your number 3 has this function M, but your equation does not contain M, what are you talking about?
