Calling multiple cell elements at once

Hello,

I have a cell something like

   A=

        [1x3 double]    [1x3 double]    [1x3 double]    [1x3 double]

Is it possible to call the first position of each vector at once? Something like

A{:}(1)

Since your A{i} are all the same size and numeric type, it is puzzling why you would maintain it in cell form, as opposed to a 4x3 matrix for example.

Hi Matt, thanks for your reply...Yes I guess I chose a bad example but I just chose a bad example for what I want to do...not necessarily all of them will be the same size still I would like to call the first position for different purposes.

Answer 1

B=cell2mat(A);
out=B(1:3:end)

Answer 2

Not with plain indexing. This one-liner does it

    r = cellfun( @(v) v(1), A )

However, ...
