How to compare two different columns with a value to check all have same values.

I have two columns with 15 rows and there value can be either all 0 or all 1 and I want to check after certain computation that there value is now 1 or not in order to terminate the computation.

Can you guide me ?

You could use the all function to perform a comparison with 1 for all elements.

For a single row, it would be

if all(x==1)
  % Continue
end

For a 2-D array, the default is that the all function operates on each column. So, if you want to check all elements across both rows:

if all(all(x==1))
  % Continue
end

Final note: If your values can only be 0 or 1, the condition x is sufficient instead of having to check the individual value x==1...
