how can I tell MATLAB to add a NaN if the size of concatenation is not consistent?

Lets say I have two matrices: A = [2,2;3;3] and B = [4,4,4;5,5,5]

I was trying to concatnate them by doing: C = [A; B]

But MATLAB threw an error saying that the dimensions are not consistent.

Now whats an easy way to fix this? The result that I would like from the example I gave previously is: C = [2,2,NaN; 3,3,NaN; 4,4,4; 5,5,5]

You could write your own function that does length matching before concatenating. Appart from that, no Idea

A = [2,2;3,3];
B = [4,4,4;5,5,5];
A=padarray(A,[0 1],nan,'post')

A = 2×3

2 2 NaN 3 3 NaN

C=[A;B]

C = 4×3

2 2 NaN 3 3 NaN 4 4 4 5 5 5
