2D array to 1D with rows appending after another row

how do i go from A =[1 2 3 ; 4 5 6] to A = [1 2 3 4 5 6]

I tried reshape(A,1,6) it gives me [1 4 2 5 3 6]

A =[1 2 3 ; 4 5 6] ;
iwant = reshape(A',1,[])

iwant = 1×6

1 2 3 4 5 6

To make the intent clearer and the code more robust, it is better to use TRANSPOSE:

reshape(A.',1,[])
%        ^^
