how to fix this code?

     A = [ 1 1 1 0 0 0 0 0 1 1
           1 1 0 0 0 0 0 1 0 1
           1 1 0 0 0 0 0 1 0 1
           1 1 0 0 0 0 0 0 0 1
           1 1 1 0 0 0 0 0 1 1
           1 1 1 1 0 0 0 1 1 1
           1 1 1 1 1 0 1 1 1 1 ]
[n,m]=size(A)
s=sum(A,2)
for k=1:n
  idx(k,1)=~isempty(strfind(A(k,:),[1 0 1]))
end
ii=s>m/2 & idx
out=A(ii,:)

when i run this code this error appear " Matrix dimensions must agree " with ii=s > m/2 & idx

We don't know what you want to get out of that code. So fixing the code, so it produces no errors is easy. Here is one way:

out = eye(10);

Since you have not said what you expect, that is as good an answer as any other.
