I have this constraint in my code.

i=number of supplier

p=type of productions

t=number of period

constraint=@NLconstraint(con1[i=1:3,p=1:2,t=1:3],E(I)[i,p,t ]=

sum(Q[i,p,s] fors=1:t)-sum(E(D)[i,p,t]+E(W)[i,p,s] for s=1:t ))

E(I)=((sigmaI/miuI)+sigmaI)*exp(((I[i,p,t]-miuI)/sigmaI)^2)

E(w)[i,p,t]=((sigmaw/miuw)+sigmaw)*exp(((w[i,p,t]-miuw)/sigmaw)^2)

they are expected value of inventory and waste of products. as well as w and I are decision variables. I would like to save all the expected value equations in one matrix[3,2,3]. Is it possible in Julia? Pleas help me. thanks all
