How to extract cell element from a multi-dimensional cell?

Hi all,

I have a multi-dimensional cell like this:

size(respPreStore)
ans =
     1     2     5     2

where each cell element is a 1*3 cell:

respPreStore{1, 1, 1, 1}
ans = 
    [12x2 double]    [2x2 double]    [4x2 double]

Now I only want all the third part in the cell, which is the 4*2 double, and store them in another cell. I tried to do this:

respPreStore{:, :, :, :}(1, 3)

MATLAB gives me error:

Expected one output from a curly brace or dot indexing expression, but there were 20 results.

Can anyone tell me how to extract these?

 cellfun({@(c)c(1,3),respPreStore)

or

 cellfun({@(c)c{1,3},respPreStore,'UniformOutput',false)

Hi Stephen,

Thanks! I was thinking about using cellfun but I thought there were more straightforward ways like directly manipulating arrays.
