How does one express the different inputs in the matrixcalc() function?

This question came up as I tried to debug why my below patch isn't working. Really, I don't even really need multiple inlets, as I'm trying to use jit.lumakey in mode 1....

/*save as moviekey.js and put in search path */

var lumakey = new JitterObject("jit.lumakey");

    lumakey.matrixcalc(inname,outmatrix); 

    outlet(0,"jit_matrix",outmatrix.name);

lumakey.fade = 0.1;
lumakey.lum = 0;
var matrixname = "movmatrix";
var usethismatrix = "";

function jit_matrix(inname){
	outmatrix.setinfo(inname);
	lumakey.matrixcalc(inname,outmatrix); 
	outlet(0,"jit_matrix",outmatrix.name);
}

well, I'm not 100% sure on this, but you should be able to send array 

lumakey.matrixcalc( [inname, in2name] , outputmatrix);

well, I'm not 100% sure on this, but you should be able to send array  
of matrix names as input to matrixcalc:

yes, that helps. thanks for the clue. for the record, here's a script that works:

var outmatrix = new JitterMatrix(4,"char",320,240);

var dummatrix = new JitterMatrix(4,"char",320,240);

    lumakey.matrixcalc([inname,dummatrix],outmatrix);
