s=[0 1];
I=[0 0;1 1;1 0;0 1;1 0;0 0; 1 0; 1 1; 0 0]
counter=0;
for n=1:size(I,1)
if I(n,:)==s
counter=counter+1;
else
%nothing to be done, just included the else for fun :)
end
end
counter
Alternative just for fun
s=[0 1];
I=[0 0;1 1;1 0;0 1;1 0;0 0; 1 0; 1 1; 0 0]
counter=0;
for n=1:size(I,1)
if I(n,:)~=s
%nothing to be done here :)
else
counter=counter+1;
end
end
counter

idx = ismember(I,s,'rows'); %row indices of matches
nmatches = sum(idx); %number of matches
row_indices = find(idx); %row numbers of matches
A few of the things you can do...

Why? nmatches will be the same result as a counted (like in Paulo's below example)
I guess this must be homework...

I was almost commenting the same you did :) your code is the best way to do it unless it's really homework.
