for i=1:5
s(i,:)=randi([0 1],1,5); 
xl=0;
xu=1860;
l=5;
si=bi2de(s);
b=(xl+((xu-xl)/((2^l)-1)))*si;
end
disp([s,si,b]);

I have a code like this. I want that if it generates s(i,:) all zero then it should terminate and start the whole process again. Please help me how can I do this.

      s(i, :) = ...
      if all(s(i, :) == 0)
         restart = true;
         break; %stop the for loop, thus restarting from scratch

Not working. Showing illegal use of reserved keyword IF

On the line

s(i, :) = ...

You actually need to put some code, just as you allocated values to s in your original code. Guillaume kindly showed you where to put this allocation, but they cannot write your code for you on your computer. This is up to you!
