Returns the result of evaluating this node and the tree below. This method has the responsability for evaluating the children of the node and it should generally call

 		MatrixValueI res = (MatrixValueI) node.jjtGetChild(i).jjtAccept(visitor,null);	
 

for each child.

Parameters:

node - The top node.

visitor - The parser visitor

jep - The current MatrixJep instance.
