How to shift a signal to left ?

Hello all ,

I have a binary stochastic signal,

N=100; x1 = 2*(rand(1,N)>0.5)-1;

and I want to shift it to the left by 9 units.. how can I do that? Tried to find some hints in MATLAB HELP but couldn't find any useful commands,,

Thanks a lot...

Hi Negar,

circshift is your friend:

circshift(x1, [1 9])

Thanks a lot Titus, but couls you please tell me how did you write that? I read the Help right now, but I can't understand the examples ..

I would like to learn it, in order to use it in future..

CIRCSHIFT does this: shifted = x1([(9+1):end, 1:9])
