i am new to javascript, and i would like to know if someone could help 

in the tutorial 46 the attractors are created inside the js object by 

a jit.noise object, i would like to replace that jit.noise by a matrix 

created outside the javascript object, so i can change the position of 

the attractors, but i don't know how to call that matrix in the js 

object. could someone help or direct me for a patch that does that?

i don't believe you would control the jit.matrix from inside the javascript, but instead pass the jit.matrix too the javascript and handle it with a function called jit_matrix.

a better approach might be to send x,y,z position information to the jit.matrices inside the javascript (for instance with a function called position(x,y,z).

otherwise, i think you can access named objects in your max patches from inside the javascript. look at the maxpatcher and maxbox js objects. my js is rusty, so this may be wrong.

Old topic, but for other people coming in...

var myMatrix;

function bang() {
    myMatrix.setall(127);
}

function anything() {
    if (messagename=="setMyMatrix") {
        myMatrix = new JitterMatrix(arguments[1]);
        post("JS set matrix "+myMatrix.name+"\n");
    }
}
