creating an empty cell

I have two matrix:

A = [1 2 3]

B = [4 5 6 7; 9 8 7 6; 5 4 3 2]

I want to combine these two matrice into:

C = [ 1 2 3; 4 5 6 7; 9 8 7 6; 5 4 3 2]

I want the top left corner to be an empty cell because in the end I want to write matrix C to a csv file so I would like to have that cell empty. I tried playing around with vertcat and horzcat but I keep getting dimensions are not consistent error.

Fill it with a Nan:

C = [[A, nan];B];

This answer will do for what I am doing but it would be nice to have an empty blank cell instead.

i also want to keep a cell blank so that when i concatenate it with the other cells it will be removed automatically.
