Problem with "LINPROG" fcion - exitflag: -2

Hello, I have a problem while using the "linprog" I repeatedly get the error message:

Exiting: One or more of the residuals, duality gap, or total relative error has stalled: the primal appears to be infeasible (and the dual unbounded). (The dual residual < TolFun=1.00e-008.)

I've seen that you blamed it on the Aeq and beq inputs, but I don't have them stated. Could this be a problem for the optimization purposes?

Many thanks for support! IvetH

Can you please show us your linprog call? I mean, something like

 [x,fval,exitflag] = linprog(f,A,b,Aeq,beq,lb,ub)

and tell us the sizes of your various input arguments.
