Good night,
I have the following item in a estructure:
U.U_1np_2np_pp;
U.U_1np_2np_pf;
U.U_1np_2np_fp;
U.U_1np_2np_ff;Then I have another processes to do and I want to systematise it. If I just write their names in the output it will print their values. But if I want to obtain their values using a loop with varget:
for hh_Ma (1,2,1);
for hh_Fe (1,2,1);
Utility =varget(U."U_1np_2np_"$+hh_prod[hh_Ma]$+hh_prod[hh_Fe]);
endfor;
endfor;the following mistake arises: G0504 : Invalid structure member
If I try the following
for hh_Ma (1,2,1);
for hh_Fe (1,2,1);
Utility =varget("U.U_1np_2np_"$+hh_prod[hh_Ma]$+hh_prod[hh_Fe]);
endfor;
endfor;This mistake shows up: G0025 : Undefined symbol 'U.U_1np_2np_pp'
How can I code this?
Thank you so much

It is usually best practice to avoid the use of varget. varget does not support the retrieval of structures or structure members. I think you would be much better off creating a vector or matrix of structure members and referencing with normal indexing. I do not know exactly what is in your structure, but here is the general concept
//Define structures
struct Udata {
matrix data;
};
struct mystruct {
struct Udata U_1np_2np;
};
//Declare 'U' to be a 'mystruct' instance
struct mystruct U;
//Reshape the 'U_1np_2np' member into an array of structures
U.U_1np_2np = reshape(U.U_1np_2np, 2, 2);
//fill in data
for i(1, rows(U.U_1np_2np), 1);
for j(1, cols(U.U_1np_2np), 1);
U.U_1np_2np[i,j].data = i + j / 10;
endfor;
endfor;
//Extract data
for i(1, rows(U.U_1np_2np), 1);
for j(1, cols(U.U_1np_2np), 1);
Utility = U.U_1np_2np[i,j].data ;
endfor;
endfor;and if it is helpful to have the pf, pp, ff, fp information, you can add that to the substruct like this
//Make sure to clear workspace since we are changing
//the definition of the 'Udata' struct
new;
//Define structures
struct Udata {
matrix data;
string name;
};
struct mystruct {
struct Udata U_1np_2np;
};
//Declare 'U' to be a 'mystruct' instance
struct mystruct U;
//Reshape the 'U_1np_2np' member into an array of structures
U.U_1np_2np = reshape(U.U_1np_2np, 2, 2);
names = ("pp" $~ "pf") $| ("fp" $~ "ff");
//fill in data
for i(1, rows(U.U_1np_2np), 1);
for j(1, cols(U.U_1np_2np), 1);
U.U_1np_2np[i,j].data = i + j / 10;
U.U_1np_2np[i,j].name = names[i,j];
endfor;
endfor;
//Extract data
for i(1, rows(U.U_1np_2np), 1);
for j(1, cols(U.U_1np_2np), 1);
Utility = U.U_1np_2np[i,j].data ;
endfor;
