The example given is just 3 rows of a matrix having half a million rows. With these 3 rows it does work fine. Its only with the large matrix that I am facing the problem mentioned
3 or 3 million, the result should be the same. The data before & after should be identical as long as the data types are the same. There is no change in the data as a result of concatenation. I still think you need to look at your code and data harder.
