maybe there is a bug in "Denoising_Guided_EI.m"? #2

"Y_hat(:,blk_arr(:,idx)) = Y_hat(:,blk_arr(:,idx)) + bsxfun(@plus, Dnew*alphanew, DC(:,idx));" 这个语句，当blk_arr(:,idx)的值相同时，Y_hat 会取出同一列，但是求和操作只起一次作用。

举例：a=zeros(3,3)；b=ones(3,2)；index=[1,1]； a(:,index)=a(:,index)+b； a = 1 0 0 1 0 0 1 0 0

应该是 "Y_hat(:,blk_arr(:,idx)) = Y_hat(:,blk_arr(:,idx)) + bsxfun(@plus, Dnew*alphanew, DC(:,blk_arr(:,idx)));"

谢谢指出我的遗漏，原因是我后来跑别的实验，代码没有改好。
