I have several struct of different dimensions in Matlab. Let us suppose that they were 5, the first is 1x100, the second 1x250, the third 1x200, the fourth 1x100, and the fifth 1x150. I want to assemble a new structure containing only the last element of the each previous structures, that is, I want to get a struct of the 1x5 form. How can I do this?

Usingendand a simple loop doesn't do the trick? Please provide a Minimal, Complete, and Verifiable example.

Do all those structs share the same format (i.e. same fields)? Don't you actually have arrays of structs which you want to concatenate?

Create 5 row vectors, then make a row vector from the last elements like this:
>> a=[1:100];
>> b=[1:250];
>> c=[1:200];
>> d=[1:100];
>> e=[1:150];
>> the_lasts = [a(end), b(end), c(end), d(end), e(end)]
sthe_last =
100 250 200 100 150
>>
That also can be generalized into a function, using a file named:
ends_of.m :
function lasts = ends_of (varargin)
% prepare a result row vector with nargin dimention
lasts = zeros(1,nargin);
for i = 1:nargin
element = varargin(i); % get the arg
last = element(end); % find the last element
lasts(i) = last; % save it as index i
endfor
endfunction
Then it can be called like this :
>> ends_of ([1,2,3],[4,5,6],[1:44], [3:33], [1,2,3,2,1])
ans =
3 6 44 33 1
>>
