Re: MathProg two-dimensional array

Hello Ralf,

please, have a look at the examples directory of the source distribution, e.g. sudoku.mod and at gmpl.pdf .

Hello everyone,

trying to define arrays with two dimensions, I could not

solve this topic in GMPL:

set ORIG;

set DEST;

set LINKS within {ORIG,DEST};

printf {i in ORIG, j in DEST} "LINKS[%s,%s] = %g \n",i,j,LINKS[i][j];

data;

set ORIG := GARY CLEV PITT;

set DEST := FRA DET LAN WIN STL FRE LAF;

set LINKS :=

(GARY,*) DET LAN STL LAF

(CLEV,*) FRA DET LAN WIN STL LAF

(PITT,*) FRA WIN STL FRE;

end;

This definition brings up this error message:

"LINKS cannot be subscripted"

So my question is: how can I define Links so, that it can be accessed

with this command:

Links[i][j]

Thanks for any comments!

Ralf
