MATLAB: Display the indices of constraints, which are satisfied with equality (Linprog)

Question

Hello together,

I'm trying to display the information, which indices of the constraints are satisfied with equality in a linear programm. I thought about to create this information by looking for the lambdas, because if there is a lambda for the equation, there is no equality. But the result isn't like expected. Do you know a good command to display this?

Thanks in advance, Pete

idx = find(A*x==b)
