Thank you for the quick response and Christopher's explanation on the design background.

you're welcome.

But if adding row build a new array, this will lead to O(n^2) complexity.

if you are adding a lot of rows one at a time, yes, you can have performance issues -- though re-allocating data is pretty fast, too -- maybe it won't matter.

If it does, consider the accumulator code I sent, or use it as inspiration to write your own.

If you do improve it, please send your improvements back to me.
