How to make a character array from loop output?

The function is mean't to generate nine random DNA sequence of different lengths (between 4 and 6 letters long), I am then supposed to sort these in alphabetical order. I'm having trouble adding the different output iterations of my loop into an array so that I can use "sort" to sort them alphabetically.

 if true
function dna = SeqGen
%Randomly generates a sequence of DNA 9 times
for i = 1:9
    k = randi([4,6],1);
    seq = randseq(k ,'Alphabet', 'dna');   
end
end

I'm not sure if i'm supposed to use char() or something else.

store them in a cell array,

 seq = cell(1,9);
 for m = 1:9
    k(m) = randi([4,6],1);
    seq{m} = randseq(k(m) ,'Alphabet', 'dna');   
 end

not sure what you mean by store them in array

Did you try the code I gave you? You should create a cell array and pre-allocate it with the size you want.

 seq = cell(1,9);

and the use it inside you loop like

 seq{m} %m =1,2,3...9

"not sure what you mean by store them in array"

KL wrote store them in a cell array. cell being the key word. See the doc. In particular, the second sentence says:

"Cell arrays commonly contain [...] arrays of different sizes"
