yes thanks a lot this was the problem.......could u please let me know if I have
two vector y1 and y2 and suppose y1 is from 1:1:10 and y2 is 11:1:20 and i want to save them in one column like 1:1:20
How I can???

i am suing this code but it is then giving me two column data which I dont want.....

y1=y(Ib-20:Ib-10);

y2=y(Ib+10:Ib+20);

yy=[y1, y2];
