concatenate cell array which contains cell array

Hello,

I have a variable A defines like this : A = cell(1,X); A{1} = {'a' 'e' 'i' 'o' 'u' 'y'}; A{2} = {'b' 'c' 'd' 'f' 'g' 'h' 'j' 'k' 'l' 'm' 'n' 'p' 'q' 'r'}; A{3} = {...}; A{...} = ... ...

I would like create a variable B which concatenates all data in the variable A in a 1 dimention cell array.

B = {'a' 'e' 'i' 'o' 'u' 'y' 'b' 'c' 'd' 'f' 'g' 'h' 'j' 'k' 'l' 'm' 'n' 'p' 'q' 'r' '...' ...};

for only A{1} and A{2}, B = cat(2,A{1},A{2}); works but it doesn't work for an unknow dimention of the variable A.

I try the cellfun but no results...

Thanks a lot,

Guillaume

Hi,

I understand you have a cell array A, which has multiple cell arrays as its members and you wish to combine all the values in cell array A into a single cell array.

Try the following code :

Step 1 - Use size() to get total cell arrays present in cell array A

X=size(A,2); 

Step 2 - Use cat function to append all the data into a single cell array

new_A=cat(X,A{;});
