As long as Mn(t) is in the form as show above, it can be treated as linear. The last equation looks hard to solve, but, i guess it is already another problem.

It simply says if each element of X is a function of variable t － 香陵居士 　2007-09-06 15:05 (46 bytes , 253reads )
this is not easy, even for linear function of t － icky 　2007-09-06 17:22 (66 bytes , 244reads )

I do understand what you mean but what's tricky here is that － 香陵居士 　2007-09-06 22:34 (120 bytes , 278reads )
if A is positive definite, then Ax > B eq to x > A^-1 B － icky 　2007-09-06 23:49 (0 bytes , 280reads )
... Can you prove that? － 香陵居士 　2007-09-07 02:00 (319 bytes , 260reads )

how do u define your AX > B ? AX is a vector, B is also a vector － icky 　2007-09-07 17:23 (117 bytes , 288reads )
oh, ok, you are saying vectors can not be compared directly － icky 　2007-09-07 12:38 (0 bytes , 259reads )
