I am new to gurobi, I have a question regarding creating an array of variables.

Question regarding how to start index with1 instead 0?

For example in gurobi, x = model.addVars(2, 3) would create six variables, accessed as x[0,0], x[0,1], x[0,2], x[1,0], x[1,1], and x[1,2].

 

Is there any way to create an array of variables staring with index 1 instead 0?

 

For example, x = model.addVars(2, 3) would create six variables, accessed as x[1,1], x[1,2], x[1,3], x[2,1], x[2,2], and x[2,3]?

  Sure: use ranges rather than numbers, for example:

  x = model.addVars(range(1,3), range(1,4), name="x")
