Splitting a 2D array

[Ajit]

Hi,

I have a 2d array with m rows and n columns and now I want to split into two smaller 2 d arrays. One 2D sub array should have x rows and n columns and the other 2 D array should have y rows and n columns where
(x + y = m).

Can any one help me in doing this,
Thanks
Ajit.
