Hi everybody, I have a vector that consists of values 0 or 1. I would like to use bootstrp with replacement to generate 100 resamples sets from this vector of the same size. Could anybody help me with this line. I am using this function but it does not give me right results: it gives me either all 0s or all 1s. Thanks

I do not see the behavior you are describing:
x= (rand(10,1)<.5);
[a,b]=bootstrp(10,@mean,x);
x(b(:,1));
x(b(:,2));
the first answer is
ans =
0

suspiciously like you described. However the second answer is
ans =
1
