combining cell arrarys to one cell

I have a cell array containing a number (say n) of 1x4 cells. I want to combine them in one cell to obtain a cell of nx4 cells. please let me know the solution.

Thanks all.

I think you want to concatenate the n cells into a simple n-by-4 array, like this

C = {[1 2 3 4],[2 3 4 5],[4 3 2 1]} % n=3 cells, each holding a 1-by-4 array
M = cat(1,C{:})  a n=3-by-4 array

And if you want to turn this into a single 1-by-1 cell array, {M} would do, but I do not recommend this ...

The cell array C contains 3 double vectors rather than 3 cells.

class(C{1})
ans =
    'double'

@ Jos and Adam, you are close to my point, i am trying get a single array holding 3 by 4 cells, how can I do that ?

[Adam Danz]

Could you provide a short, precise example of what your data look like before the transformation and what you want it to look like after the transformation?

[carl hooper]

Thanks, Josand Adam, your help worked, only for Adam's case there was an unncessary space whigh resuted into an error. Have a good day guys !!

[Adam Danz]

Where was there an unnecessary space? Your line that worked is identical to my suggestion.

Here's a demo using fake data.

t = {{1:4}',{1:4}',{1:4}'};    %also works if t is columnar
m = cell2mat([t{:}]')
m =
     1     2     3     4
     1     2     3     4
     1     2     3     4

[carl hooper]

Thanks, I copied your lines but An error comes up showing unexpected matlab operator. I got the correct one as

cell2mat([t{:}]');

[Adam Danz]

That's identical to my 2nd line. The first line in my response is just producing fake data. Glad it worked!
