Hi Miguel
with no further information the following does what you ask for
U=randi([-10 10],1,10)
=
7.00 9.00 -8.00 9.00 3.00 -8.00 -5.00 1.00 10.00 10.00
Select a p such is smaller that at least length(U)-1, for instance
p=3
the limit for the sum is
L=length(U)-p
L =
7.00
and now let's calculate S
S=zeros(1,L);
for k=1:1:L
S(k)=sum(U([1:k+p]));
end
17.00 20.00 12.00 7.00 8.00 18.00 28.00
Since T does not show the vector arrow I understand it's a scalar, so to complete just multiply
S=T*S
If T is a vector, then you could either multiply element by element with
S=T.*S
provided T and S have same size
