How to combine vectors of different length into matrix ?

Actually..what I want to do is...

I have a vector A =[ 1 2 3 4 5] and a matrix B = [3 4 5 0 0; 1 2 4 5 0; 4 5 0 0 0]

I want save setdiff(A,B(i,:)) i.e. difference of each row of B from A

[1 2] , [3], [1 2 3] into a matrix in the form of [1 2 0; 3 0 0; 1 2 3] (padding with '0')

Please help....

Thanks...

I would just use a for-loop and some fun indexing:

A =[ 1 2 3 4 5];
B = [3 4 5 0 0; 1 2 4 5 0; 4 5 0 0 0];

sz = size(B);
C = zeros(sz);
nkeep = -inf; %how many columns to keep?
for ii = 1:sz(1)
  temp = setdiff(A,B(ii,:));
  ncurr = numel(temp);
  nkeep = max(nkeep,ncurr);
  C(ii,1:ncurr) = temp;
end
C = C(:,1:nkeep);

Just for fun.. Another complicated way..

A =[ 1 2 3 4 5];
B = [3 4 5 0 0; 1 2 4 5 0; 4 5 0 0 0];

for ii=1:size(B,1)
c(ii,:)=[setdiff(A,B(ii,:)),zeros(1,length(B)-length(setdiff(A,B(ii,:))))];
end
c
