MATLAB: How to solve this error”Dimensions of matrices being concatenated are not consistent.”

dimensions of matrices being concatenated are not consistent

This error is happened when I used this number in matrix.

Look at this example. A has 3 elements,
>> A = [1 2 3]
A =
       1     2     3
B has 2 elements,
>> B = [4 5] 
B =
       4     5
now concatenate them horizontally (side by side)
>> C = [A B] 
C =
       1     2     3     4     5 % now C has both A and B
now try vertical concatenation, (up and down)
>> C = [A;B]
Error using vertcat
Dimensions of matrices being concatenated are not consistent.
Why? Because, A has 3 elements wherein B has only 2. This is what is meant by "Dimensions are not consistent. Now let's say B also has 3 elements...
>> B = [4 5 6]
B =
       4     5     6
now try again,
>> C = [A;B] 
C =
       1     2     3
       4     5     6
works. Do you understand your problem?
