Hi, I have the following code:

for m=1:10

        for n=1:sz(2)
            if(Isingle(m,n)==1)
                index1=[m n];
                break;
            end
        end
    end

I need to exit from the entire for loop i.e. for m=1:10 and for n=1:sz(2) when any index value is found, i don't know how to do that. can any body help?

Thanks

[i1 j1] = find(Isingle' == 1, 1, 'first')

OR with loops

for m=1:10
   for n=1:sz(2)
       if(Isingle(m,n)==1)
           index1=[m n];
           return
       end
   end
end

Hi,

I think you have to use a flag

flag = 0
for m=1:10
        for n=1:sz(2)
            if(Isingle(m,n)==1)
                  index1=[m n];
                  flag = 1
                  break;
              end
         end
         if flag == 1
            break;
         end
end
