    Hello,
    i am in the process of learning how to use javascript with jitter. at the moment i am stuck with a seemingly very basic problem. I want to place on (smaller) matrix inside anothe (bigger one) to achieve somthing similar like in the patch below.
    My problem is: how do i fill on matrix into another using javascript. my javascript code is something like that
    var smallmatrix = new JitterMatrix(4, "char", 320, 240); var largematrix = new JitterMatrix(4, "char", 720, 450);
    largematrix.usedstdim = 1; largematrix.dstdimstart = [10, 10]; largematrix.dstdimend = [330, 250];
    //[some foo filling the small matrix]
    function bang() { // and here starts my problem. If I use: largematrix = smallmatrix; // the largematrix is just identical to the smallmatrix. //is there a function that i can use?

      I don't have much time to write up a fresh example, but perhaps this will help you:
      var noiz = new JitterObject("jit.noise");
noiz.type = "char";
noiz.planecount = 1;
noiz.dim = [4, 4];
noiz.name = "noisay";

function bang()
{
  copymat(noiz);
}

function copymat(iname)
{
  var input = new JitterMatrix("inamed", iname.planecount, iname.type, iname.dim);
  var output = new JitterMatrix("outr", iname.planecount, iname.type, iname.dim);
  noiz.matrixcalc(input, output);
  outlet(0, "jit_matrix", output.name);
}
