%%?功能：融合xy兩行向量（經(jīng)典Dempster-Shafer組合公式）
%?xy的格式形如[m1?m2?m3?...??mk?m（全集）?m（空集）]
%?要求m1?m2?m3?...之間互相無交集
%?m（全集）可不為0，表示不確定度
%?m（空集）肯定是0
%%?%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%?（前一行，后一行）
function?x=DS_fusion（xy）%%?DS_fusion（1*6??1*6）
%%?判斷輸入x、y為行向量；列數(shù)相等
[nxmx]=size（x）;
if?1~=nx
????disp（‘x應(yīng)為行向量‘）;
????return;
end
[nymy]=size（y）;
