function [valindex] = NumconvertCard(num,length,AccCard)% This function converts a vector of variables num, where the accumulative cardinality of each variable is in AccCard,% to the index valindex corresponding to the vector.% AccCard is the product of cardinalities of previous  variables, where the first variable is  the one to left.  valindex = num(length);     for i=1:length-1,   valindex =  valindex +  num(i)*AccCard(i); end
