How to format a cell array

Hi,

Quick question here. I have a 1x15 cell which contains 15 24x1 double (i.e 15 cells, each containing 24 numbers). Is there an easy way to convert this into any other format? Say a 1x360 cell ? Or anything else that's actually easy to use?

Thank you

% pre-process to get data
tempcell = cell(1,15);
for i = 1:15
    for j = 1:24
    tempcell{i}(j,1) = rand(1);
    end
end

% tempcell = 1 * 15 cells with 24 *1 elements in each cell

% format all cell elements into a array
Singlearray = reshape(cell2mat(tempcell),[],1); % sort to a column vector
Singlearray2 = reshape(cell2mat(tempcell),1,[]); % sort to a row vector

Let me know if this is what you want, Gopi

The simplest would be as a simple numeric array, so use:

 cell2mat(X)

Or, if you really want a cell array, then try:

 num2cell(cell2mat(X))

possibly followed by a reshape. Personally I would just put the data into one numeric array: much simpler and faster to work with.

Whatever you do do not use loops for this. Loops are a slow and inefficient way to solve tasks like this.
