b=[1;2;3;4;5;6;7;8;9;10;11;12;13;14;15];
a=zeros(3,1);
c=([a;b]);
d=(c(1,1):c(6,1));
e=(c(4,1):c(9,1));
please suggest me the way how can i write the code for vector d and e.
i want d vector as; d= [0;0;0;1;2;3] and
vector e as ; e=[1;2;3;4;5;6]

b = [1;2;3;4;5;6;7;8;9;10;11;12;13;14;15];
a = zeros(3,1);
c = [a; b]
c = 18×1
0 0 0 1 2 3 4 5 6 7
d = c(1:6,1) % ",1" not necessary since c only has one column
d = 6×1
0 0 0 1 2 3
e = c(4:9) % ",1" omitted
e = 6×1
1 2 3 4 5 6

That uses the value of Utdelt that was calculated for n=5. Previously calculated Utdelt values, i.e., for n=1 through n=4, are not used. Maybe that's what's wrong.
