Suppose I have the following code

for n = 1:21
    sz = [23,42000];
    data = cell(sz);
    for k = 1:12
        x=foo( );
        data{k}=x;
    end
end

after its being executed I get a cell named data which has 12 1x69 arrays like this

1x69 double

Now I want to save this in an array outside of inside for and also add to this array the following 12 1x69 arrays for the end 20 itterations of the outside loop.

Eventually, I want to have 12x21=252 1x69 arrays in a single array 252x69.

I hope you guys understood what I am asking and I wish someone out there help me here, because I am clueless here...

What is 'y' here?

Ignore y , I'm removing it. Suppose foo is just providing values for cell

Dear Stamatis, here is code for converting cell array into a matrix:

for i = 1:12
    data{i} = rand(1, 69); % create cell having 12 arrays of 1x69
end
a = reshape(cell2mat(data), [], 69); % storing the arrays in a matrix

Is it what you need?

it does something interesting, I think its close to what I am looking for, I am going to work it out a bit and hopefully get the desired results. Thanks !
