Is there a way to know if constraints are not too restricitve.

Hi everyone,
I was wondering, given a constraint type a.x =<b
Is there a quick way to know if the boundaries are not too restrictive to allow at least one solution?
Given an easy example:
[0 0 -1 -1 -0.5; -1 -1 0 0 -0.5; -1 -1 -1 -1 -1; 1 1 1 1 1]
Thank you!

If you know it to be a bounded feasible set, you can check if it has a non-empty set of vertices using LCON2VERT in

Then you should restore your question back to its original form. You are asking about whether the feasible set is empty/nonempty, not whether the feasible set is bounded/unbounded.
In any case, you have both answers, but it is practical mainly for low dimensional problems.
