is that right?
but Error when entering data
it shows
Obj([10 1 -1;2 6 1],[10 1 -1;2 6 1],20,[-2; -11])
ERROR: UndefVarError: X not defined

thank you!
You are more likely to get help if you post the code in a way that other users can copy and paste into their own terminal.

using JuMP
using SCIP
function Obj(SC,SB,B,C)
text = Model( with_optimizer(SCIP.Optimizer))
@variable(text,X[1:2],0<=X<=100,Int)
@objective(text,Min,C'*X+B)
@constraint(text,SC*X'.+SB<=0)
optimize!(text)
end
ok,i will,thanks
I think this should be (untested):
@variable(text, 0 <= X[1:2] <= 100, Int)
Also, in your constraint, you should probably use .<= since you have a vector on the left-hand side, right?
