Extracting a vector from elements of a matrices that are in a cell structure.

Hi,

I have written this simple program:

C = {[1,2],[3,4],[5,6]},C{1},C{2},C{3},V=[C{1}(1),C{2}(1),C{3}(1)],V2=[C{1}(2),C{2}(2),C{3}(2)],

and the answer is V1=[1,3,5],V2=[1,3,5].

But if I write in a compact way, let us say:

V=[C{1:3}(1)] 

it doesn't work. The result is:

"Expected one output from a curly brace or dot indexing expression, but there were 3 results."

How to fix it?

Thanks!.

What is your desired output? [1;3;5]?

Some wrong information was written in my previous e-mail, sorry.

It should be V(or V1)=[1,3,5],V2=[2,4,5].

How to write in a simple sentence without the use of "for ---- end"?

V = cat(1,C{:});
V(:,1)'
V(:,2)'

It works, thanks so much!
