Dear all,  
Could anyone provide a simple example of how can I use MIP starts in integer programming in Julia language?  
I have a problem and a feasible solution, but I cannot to use this solution inside of the CPLEX.  
For example, if I have the problem

max x[1] + x[2] + 3x[3]  
st x[1] - 2x[2] + 3x[3] \<=5  
x[1] + 5x[2] \>= 3  
x[3] \<=2  
x[i] integer, i=1,2,3  
and I want to provide the vector v = [1,1,1] as initial solution for the CPLEX. There is a way to do this?  
I thank you for the help.  
Best regards,

---
