Hi
Use the ismember function
Possible solution will look something like this:
[r,c] = size(matrix) ;
k = 1:r;
for i=1:r
# remove the zeros
rowvec = matrix(i,:)(matrix(i,:) > 0);
for ii=k(k != i) # To ensure not to compare the same vectors
X = matrix(ii,:)(matrix(ii,:) > 0 );
# a takes 0 or 1
[a,b]=ismember( rowvec , X );
end
end
assuming you constructed a matrix from your vectors and padding it with
zeros for equal column dimension.
Havnt tested it yet, but should point in the right direction.
Cheers
Fernando
