I'm trying to extend an Array into a 2D matrix. Any suggestions? The following code fails but I don't understand why.
public class MatRix extends Array { public function MatRix(numRows:int=0,numCols:int=0) { super(numRows); for (var i:int=0;i<numRows;i++) { for (var j:int=0;j<numCols;j++) { this[j]=new Array(); } } }
