How do I assign rows of a matrix to an array?

So I have a Matrix, say A =[1,2,3;4,5,6;7,8,9]
I need to create an array of [4,5,6;7,8,9]
I have been trying a thousand variations of B= num2cell(A(2,:)) and B= num2cell(A(3,:))
but all I can create is obviously just an array of either 4,5,6 or 7,8,9 not them combined.
Any advice?

Don't mess with cells - too complicated. Just index the rows:
b = A(2:3, :) % Extract rows 2 to 3 only.

B= num2cell(A(2:3,:))

2:3 means from 2nd row until 3rd row of that matrix
