How to sequentially generate a vector from loop?

Hi everyone!
I have a vector A, which I cut in a loop and take the first elements like this
A = [ 1 2 3 4 5 6 7]'
for k=1:7
A_{k} = A(1:k)
end
I want to generate a vector B which can put a subset of A (let's say the first 2 elements (A_{2}')) together with the last element of every generated vector from my loop. Basically B should be like this
B = [A_{2}' A_{3}(3) A_{4}(4) A_{5}(5) A_{6}(6) A_{7}(7)]'
How can I make this vector B easier to write for bigger k's (for example write it like a loop) ?
Thank you so much!

"but if there's another function in the loop"
For example?
"I just want to create a vector B, which contains first 2 elements of A and every time it adds the last element of a for loop"
Give another example, as it is not clear from the one you gave.

It's not clear what exaclty is your problem. But maybe something like this can help you:
s=2
for k=1:7
A_{k} = A(1:k);
if k==s
B = [A_{2}']
elseif k>s
B = [B' A_{k}(k)]'
end
end
Try to get the details right yourself.
