# Perturbation of Linear Programs

Consider the linear program,

$$\begin{array}{ll} \text{maximize} & c^T x\\ \text{subject to} & Ax \leq b\\ & x \geq 0\end{array}$$

I want to study the sensitivity of the optimal $x^*$ with small perturbations to the matrix $A$. Most of the results I can find consider sensitivity with respect to $b$. Can some one point me to the relevant literature?
