There is a constraint “P=Q./R”, where P and Q are vector{variableRef}, Q is array{Float64,2}

JuMP model is as follow:

```
using JuMP,Gurobi,LinearAlgebra
model=Model(Gurobi.Optimizer)
Q=[1,2,3]
@variable(model, P[1:3])
@variable(model, R[1:3])
@expression(model, expr1[i=1:n],Q[i]/R[i])
@constraint(model, con1[i=1:3], P[i]== expr1[i])
```

Error: / is not defined?!

How could I solve it using @expression not @NLexpression and with Gurobi solver?
