Hi, I want to shift my data stream to the right by 1 and left by 1. It is reading from a csv file. I was thinking about using cir sift but I am not sure if that is the best way.

Depends on what you mean by shifting my data. Can you give a numerical example of input/output

Sure, I have a [1 x 1000]double for inputted output with values and I want to test out the way that the rest of the code interacts by shift the said input, outputs to the right and to the left

Since your vector is a column vector, shifting left or right (e.g. with circshift) will result in the exact same vector, while a row vector will not:
ans =
ans =
3 1 2
Read the doc for circshift to understand what it does. (and it is always easier to understand a function when you enter small inputs)
