matrix to message object in mxj
Hi everyone!
quick (and hopefully simple-to-answer) question…
I would like to use a jitter object within my mxj code that doesn’t return a matrix, but does analysis and spits out numbers. Specifically, I want to use jit.findbounds, which spits out two pairs of numbers for the min and max bounding vertices. How can I get a hold of these numbers in Java code? do I still use the matrixcalc() method, or is there something else? (i.e. a message to call/send)
I’ve tried setting the second argument of matrixcalc() to being both a String (no result) and an Atom[] (compile error), in case it returned data that way. Nope.
Any suggestions appreciated…

If I remember correctly jit.findbounds is not available in Java.
Hi
maybe it’s a bit late now:) but it works for me with the output argument to matrixcalc() as null:
import com.cycling74.jitter.*;
import com.cycling74.max.*;
public class myfb extends MaxObject {
private JitterObject fb;
public myfb() {
declareInlets(new int[] {DataTypes.MESSAGE});
declareOutlets(new int[] {DataTypes.LIST, DataTypes.LIST});
setInletAssist(0, "(matrix) in");
setOutletAssist(new String[]{"(list) min bounds", "(list) max bounds"});
declareAttribute("min", "getMin", "setMin");
declareAttribute("max", "getMax", "setMax");
fb = new JitterObject("jit.findbounds");
}
private Atom[] getMin() {
return fb.getAttr("min");
}
private void setMin(Atom[] a) {
fb.setAttr("min", a);
}
private Atom[] getMax() {
return fb.getAttr("max");
}
private void setMax(Atom[] a) {
fb.setAttr("max", a);
}
public void jit_matrix(String in) {
fb.matrixcalc(in, null);
outlet(1, fb.getAttr("boundmax"));
outlet(0, fb.getAttr("boundmin"));
}
@Override
protected void notifyDeleted() {
fb.freePeer();
}
}hth!
