Hi Riley, This condition is not necessary.I changed the type of the variable. M = m.addMVar((p, q), vtype="B", name="M")scalars = m.addMVar((q, p), lb=-float("inf"), name="scalars")e_scalars = m.ad...

How to use gurobi to describe the process of finding the rank of matrix without objective function?
AnsweredIf have a general square matrix[[1,1,0],[1,1,0],[0,0,0]].(the element is on a binary field--Galois Fields) I want to find the rank of this matrix(like the function:np.linalg.matrix_rank). How can d...

Actually,this line always have an error m.addConstr((e_borrowed == 0) >> (e_scalars.transpose()==0)) File "src\gurobipy\model.pxi", line 3623, in gurobipy.Model.addConstr File "src\gurobipy\mline...
