The problem is that you are clearing the mat5 container every time the while loop runs. If you move it out of the while loop, it should fix the problem.
Edit: The K is also being set to 1 every time the while loop runs. This means after the first iteration of the for loop. K will equal 1 k=1 and will overwrite your previous data.
