Re: [Help-glpk] Subscript problem , out of domain error

[Luiz Bettoni]

The data for param Matrice was transposed.
Change the line to
    param Matrice (tr) : Z1  Z2  Z3 :=
(see mod attached).

Anteriormente, em 16:59, Alessandro Urbano havia escrito o seguinte:

What's the problem with this minimal code?
I have some trouble accessing in subscript a matrix

That's the code :

set Ale;

set Alb;

param Matrice{i in Ale,j in Alb};





solve;

display Matrice[1,1];


data ;





set Ale := Z1, Z2, Z3;

set Alb := X1, X2, X3;

param Matrice : Z1  Z2  Z3 :=
X1               8   2   8
X2               7   3   1
X3               6   5   4;


end;
