I want to find the discrepancy of scores.
Lets say there are three scores:
S1 = [0 1 0 2 4 3 1]
S2 = [1 1 0 4 4 3 0]
S3 = [0 2 0 4 4 1 1]
I want to find the indices of the columns where there are 1 or 2 zeros (the first and seventh column in the example). So the logical array should I want to get should be:
logical1 = [1 0 0 0 0 0 1]
idx1 = [1 7]
Also I want to find the indices of the columns where there is a difference of 2 or more between any two scores (the fourth and sixth column in the example). So the logical array should I want to get should be:
logical2 = [0 0 0 1 0 1 0]
idx2 = [4 6]
Can anyone help me out?

S1 = [0 1 0 2 4 3 1] ;
S2 = [1 1 0 4 4 3 0];
S3 = [0 2 0 4 4 1 1] ;
Q=sum(~[S1;S2;S3]);
logical2=Q==1 | Q==2
logical2 = 1×7 logical array
1 0 0 0 0 0 1
Q=find(abs(S1-S2)>=2 | abs(S2-S3)>=2 | abs(S1-S3)>=2)
Q = 1×2
4 6
