How can I convert a matrix to a list in Mathematica?

[johnobono]

Hi everyone:

I would like to join all elements of on matrix into just one list:

matrix =
1 2 3
4 5 6
7 8 9

into

list = {1,2,3,4,5,6,7,8,9}

Anyone has a solution for this?

Thanks

list = Flatten[matrix]

OMG! Thanks, such a simple solution. I tried a lot of things, such as "For" and "Join", but with no easy result.

Thank you very much!
