how to shift arrays to the right??

for example i have :

arr=[1 0 1 1 0 0 0 1];i want to shift it one step to the right and add a random bit to the left

my array will be ike this arr=[? 1 0 1 1 0 0 0]

?: could be 0 or 1 .

Easiest way:

bit = (rand > 0.5);  %create random bit
arr = [bit, arr(1:end-1)];

@Matt: Please post this as an answer, such that I can vote for it and mary can accpet this "easiest" soluion.

@mary: The tags are used to classify the questions. As long as almost all questions concern "matlab function"s, this is not a useful tag.

How can you do this with a for loop

Answer 1

[Thorsten]

arr = [round(rand(1,1)) arr];

Answer 2

[Nathan Hall]
