% Find the best matches
err=zeros（1length（Ipts1））;    %%D1中每个行向量与D2中匹配向量之间的距离
cor1=1:length（Ipts1）;    %%D1的顺序索引值
cor2=zeros（1length（Ipts1））;   %%D2对应D1每个行向量的索引值
for i=1:length（Ipts1）
    distance=sum（（D2-repmat（D1（:i）[1 length（Ipts2）]））.^21）;
    [err（i）cor2（i）]=min（distance）;%% err（i）最小值;cor2（i）索引
end

% Sort matches on vector distance
