Hi~
Does the array can be two dimension in script language?
it only mentions one dimensional array in the Language Reference Manual.
I need use two dimensional array but i cannot declare it and use it. 
can anybody teach me? thanks a lot!!!

//parameters
int n=...;
float Dis[1..n][1..n]=...;
int a[1..n]=...;
//int row;
//int column;
//float D[1..row][1..column];
//transform
execute {
var row ;
var column;
D= new Array()();


row = 1;
for(var i=1; i<=n; i++){<br /> if(a[i]==1){
column=1;
for(var j=1;j<=n;j++){<br /> if(a[j]==1){
//writeln(Dis[i][j]);
D[row][column]=Dis[i][j];
//D[row][column]=Dis[i][j];
//writeln(row);
//writeln(column);
column++;
}
}
//row++;
}
row++;
}
}

Two dimension arrays in ECMA-Script are arrays of arrays:

var a2 = new Array();

for (var i=0; i<n; i++) {<br />  a2[i] = new Array();
  for(var j=0; i<n; j++) {<br />    a2[i][j] = ...
  }
}

Tschau,
Frank

Hi Frank

I just copy and past your code and still cant use it this way:

var a2 = new Array();

for (var i=0; ii<3; ii++) { a2ii = new Array();
for(var j=0; ii<3; jj++) { a2iijj = 10;
}
}

for (var ii=0; ii<3; ii++) {
for(var jj=0; ii<3; jj++) {
writeln("a2 =",a2iijj);
}

}

what I have to do?

Thanks.

The condition check in your inner 'for' loop seems to be the problem. Could you try using the following instead:

execute{
        var a2 = new Array();
        for (var i=0; i<3; i++) { 
                a2[i] = new Array();
                for(var j=0; j<3; j++) { 
                        a2[i][j] = 10;
                }
        }
        for (var ii=0; ii<3; ii++) {
                for(var jj=0; jj<3; jj++) {
                        writeln("a2 =",a2[ii][jj]);
                }
        } 
}
