Setting initial values of a three dimensional optimization variable

Hello,

I want to set the initial values of a three dimensional optimization variable, but not getting any perfect documentation about that. A sample code is given below.

m = Model(with_optimizer(Ipopt.Optimizer));
@variable(m, v[1:3, 1, 1:2]); 

The initial values I want to set are as follows.

v[:,:,1]=[4; 5; 6]
v[:,:,2]=[7; 8; 9]

Now, how can I initialize the variable v in this optimization problem?

Thanks in advance!
