How to concatenate elements in cell array to a vector?

I have cell arrays with different size & I want to concatenate all the elements in the cell to become a vector. How to do that?

This is my code:

% Create cell arrays
Q= [23 34; 44 55; 56 71; 63 49; 71 30];
B= [12 13; 10 99];
C{1}=Q;
C{2}=B;

% Convert cells to vector
nCol   = cellfun('size', C, 1); 
nRow   = numel(C); 

No_of_elements = cellfun(@numel, C); 
P = No_of_elements(1,1) + No_of_elements(1,2); 
Output = NaN(1,P); % Size vector

for iC = 1:numel(C)
  idx = (iC - 1) + 1;
  Output(1:P(iC), idx:idx+1) = C{iC};
end

I want the final output to become, Output = [23 34 44 55 56 71 63 49 71 30 12 13 10 99]

Q= [23 34; 44 55; 56 71; 63 49; 71 30];
B= [12 13; 10 99];
C{1}=Q;
C{2}=B;
Output = reshape(vertcat(C{:}).',1,[])

Output = 1×14

23 34 44 55 56 71 63 49 71 30 12 13 10 99

Thank you, I get the vector.

If I change the cell array Q to [23 34 10; 44 55 45; 56 71 32; 63 49 55; 71 30 11] and cell B still the same, I get an error :the dimension arrays being concatenate are not consistent. How to concatenate all the elements?

Q and B are not cell arrays. If you have them by themselves then

Q = [23 34 10; 44 55 45; 56 71 32; 63 49 55; 71 30 11];
B = [12 13; 10 99];
output = horzcat(reshape(Q.',1,[]),reshape(B.',1,[]))

output = 1×19

23 34 10 44 55 45 56 71 32 63 49 55 71 30 11 12 13 10 99

If they really are elements of a cell array

C{1} = Q;
C{2} = B;
output = horzcat(reshape(C{1}.',1,[]),reshape(C{2}.',1,[]))

output = 1×19

23 34 10 44 55 45 56 71 32 63 49 55 71 30 11 12 13 10 99

Probably other solutions as well.

Thank you so much. I get it
