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 think the examples in 3 can still be treated as linear. － bugzzj 　2007-09-25 10:26 (236 bytes , 363reads )
i'm still confused － icky 　2007-09-06 12:40 (100 bytes , 314reads )
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 , 254reads )
this is not easy, even for linear function of t － icky 　2007-09-06 17:22 (66 bytes , 244reads )
i mean － icky 　2007-09-06 17:22 (68 bytes , 265reads )
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 , 281reads )
... Can you prove that? － 香陵居士 　2007-09-07 02:00 (319 bytes , 260reads )
Thanks, but the most important thing is － 香陵居士 　2007-09-08 09:29 (173 bytes , 256reads )
aiyah.... － icky 　2007-09-08 01:40 (114 bytes , 244reads )
As I described － 香陵居士 　2007-09-08 00:19 (161 bytes , 267reads )
how do u define your AX > B ? AX is a vector, B is also a vector － icky 　2007-09-07 17:23 (117 bytes , 290reads )
oh, ok, you are saying vectors can not be compared directly － icky 　2007-09-07 12:38 (0 bytes , 261reads )
