Not quite sure what you are asking.
A search for "Double Matrix" brings up a lot of math problems, where the number of objects meeting a certain description is solved by grouping the objects by 2 (or more) parameters.
A search for Double Matrix Lottery produces a lot of links that talk about games with a main set of numbers drawn from one matrix and a bonus number (or numbers) drawn from a second matrix.
I didn't come across anything that I could relate to picking lottery numbers.
Do you have a link or further information?
Good luck!
