CPLEX's LP and MIP solvers and linprog and intlinprog solvers of MATLAB - comparison - Reg

4 views (last 30 days)
I solved a linear programming problem by modeling in GAMS modeling language and used CPLEX's lp and MIP solvers. This problem has around 1800 variables.
The same problem i modelled in MATLAB and used linprog and intlinprog solvers.
There is lot of variation in the results obtained from the two modelling environments ( GAMS and MATLAB with CPLEX and MATLAB solvers).
I want to know the reason.

Never mind my previous suggestion. I forgot that this was linprog. But you can still compare the objective function difference
>> dot(f,x1-x2)
