I constructed a linear model in JuMP by loading an .lp file.
lp = Model(solver=CPLEX.CplexSolver())
lp.internalModel = MathProgBase.LinearQuadraticModel(lp.solver)
I wonder if there is anyway to get the constraint matrix of this LP model, i.e., how to get the coefficients of this LP model in Julia?
Thanks in advance!
