for example: I have a column vector as [1200 1260 1320 1380 1440 1500 1560 1620......] I want to add a value 0 to 1200, 15 to 1260, 30 to 1320,45 to 1380 then again 0 to 1440, 15 to 1500, 30 to 1560, 45 to 1620...... and so on, such that only 4 values have to be added to a big column of infinite elements, but repeatedly.., plz help me come out

This is easy using mod, no loops are required (and would be slow and inefficient anyway):
>> X = [1200;1260;1320;1380;1440;1500;1560;1620]
X =
1200
1260
1320
1380
1440
1500
1560
1620
>> V = 15*mod(0:numel(X)-1,4);
>> X+V(:)
ans =
1200
1275
1350
1425
1440
1515
1590
1665

a = [1200 1260 1320 1380 1440 1500 1560 1620] ;
a0 = [0 15 30 45 0 15 30 45] ;
N = length(a) ;
iwant = zeros(N,4) ;
for i = 1:N
iwant(i,:) = linspace(a0(i),a(i),4) ;
end
iwant = reshape(iwant',[],1)
