由对赌博的思考引起的关于线性不等式组的问题。

对于一个线性不等式组
AX > B                      (1)
其中X = [x1 x2 ... xn]T, A(n*n),B(1*n)为确定的实矩阵。

1。任意给定向量 K = [k1 k2 ... kn],如何确定MX的符号
2。对于向量 L = [l1(t) l2(t) ... ln(t)]T,其中ln(t)=ln1 x + ln2 (ln1, ln2是确定的实数),如何确定满足(1)的t的范围。
3。一般情况,对于 M = [M1(t) M2(t) ... Mn(t)],其中 Mn(t)是关于的确定代数函数,如何确定满足(1)的t的范围。

哪位知道要解决这三个问题应该阅读哪些方面的书籍?谢谢!

please explain your notation icky   (405 bytes , 299reads )
Sorry... so many typos... 香陵居士   (276 bytes , 391reads )
I think the examples in 3 can still be treated as linear. bugzzj   (236 bytes , 360reads )
i'm still confused icky   (100 bytes , 311reads )
It simply says if each element of X is a function of variable t 香陵居士   (46 bytes , 253reads )
this is not easy, even for linear function of t icky   (66 bytes , 242reads )
i mean icky   (68 bytes , 264reads )
I do understand what you mean but what's tricky here is that 香陵居士   (120 bytes , 274reads )
if A is positive definite, then Ax > B eq to x > A^-1 B icky   (0 bytes , 279reads )
... Can you prove that? 香陵居士   (319 bytes , 259reads )
Thanks, but the most important thing is 香陵居士   (173 bytes , 255reads )
aiyah.... icky   (114 bytes , 241reads )
As I described 香陵居士   (161 bytes , 266reads )
how do u define your AX > B ? AX is a vector, B is also a vector icky   (117 bytes , 285reads )
oh, ok, you are saying vectors can not be compared directly icky   (0 bytes , 257reads )
