Hello Asmâ,
please, have a look at glpk-4.47/doc/gmpl.pdf contained in the
source distribution of GLPK, available at
ftp://ftp.gnu.org/gnu/glpk/glpk-4.47.tar.gz
You can use the following syntax:
# dimensions of "vector"
set D := {1..2};
# elements of "vector"
set X{D};
display X;
data;
set X[1] := 1, 2;
set X[2] := 3, 4;
end;
For loading data from CSV or from a SQL data base have a look at
the table statement.
Best regards
Xypron
