$A$ is a $n\times n$ positive-definite matrix and $x$ is a $n$-vector.
$\overrightarrow{0}=(0,0,...,0)^t$ and $\overrightarrow{1}=(1,1,...,1)^t$
How to solve the inequalities system$\overrightarrow{0}\leq Ax\leq \overrightarrow{1}$, i.e, there are $n$ inequalities and the $i$-th one is:
$0 \leq A_{i1} x_1$+$A_{i2} x_2$+....+$A_{in} x_n \leq 1$.
Many thanks for the helps.
