[SciPy-User] How to check inequalities for contradiction

Hi,


I have a System of inequalities like this


Ax + b >= 0


where the Relation ">=" is meant to hold in every line of the equation
system. Additionally, every element of x has to be nonnegative.

Say

m,n = A.shape

thus

len(x) == n
len(b) == m

I have m > n.

What would be the preferred way to test whether a solution exists?
In other words, I want to test that there is no contradiction in the
system of inequalities.


The main intention of this post is to figure out whether a
out-of-the-box solution to this type of problems exists.

Thanks in advance.
Bastian.
