MATLAB: Filter out incorrect responses

MATLABoutliers

If I have a dataset, in which the correct response was 1 and the incorrect response was 0, how can I filter out the participants with incorrect responses? I have to write this as a script in matlab.
Thanks.

If the responses are integers, and if I understand your problem correctly, this will work:
subjects = 1:10;
responses = randi([0 1], 1, 10);
subj_resp = [subjects; responses]
keep_responses = find(responses == 1)
subj_resp =
       1     2     3     4     5     6     7     8     9    10
       0     1     0     1     1     0     1     0     0     1
keep_responses =
       2     4     5     7    10
