Solving my mixed integer linear problem I have faced matrix singularities. I have excluded almost all problems, but I don't know a short way to exclude rows which are similar (as shown) to each other and they cause a singularity problem.
So if we have in matrix A two rows from all like this;
x1 - x2 < 0 and
2*x1 - 2*x2 < 0
So the second inequality is just multiplied by 2, but it could be any real number.
So I have to find all this kind of similarities in a matrix size 1000(rows) * 768 (columns)
I am using matlab, if someone knows if the is any command which does this directly is even better.
Thank you for your help.
