MATLAB: Match with ismember function

ismembermatchingvector

Suppose I have a matrix and a vector,
Mat= [1 343
      3 655
      4 565
      7 676]
and a vector
v = [1 2 3 4 5 6 7];
I want output as
out [1 343
     2 0
     3 655
     4 565
     5 0
     6 0
     7 676]
I am trying to use
[~,idx] = ismember(v,(Mat(:,1)))
out = Mat(idx,:)
This doesnot work

Best Answer

idx=setdiff(v,Mat(:,1)).';
idx=[idx zeros(numel(idx),1)];
res=sortrows([Mat;idx])
