The forEach() method sends as a parameter to the function, the content of the relevant position of the matrix, not the index.
What you are looking for looks like this:

var array=[[1,2,3],[4,5,6],[7,8,9]];

array.forEach(function(indice){
    indice.forEach(function(index){
       console.log(index);
    });
});
