Create a new vector by adding and subtracting each element of original vector.

Hello community,

I want to create a new vector by adding and subtracting each element of orginal vector. How can I do?

Example: A = [3 8 99 61]

What I want is: Output B = [2 3 4 7 8 9 98 99 100 60 61 62]

B = reshape(A + [-1;0;+1],1,[]) % or
B = reshape(bsxfun(@plus,A,[-1;0;+1]),1,[]) % if < = 2016a

+1, The first line is clearly best

For releases prior ro r2016b, you can use a variant of the first line and avoid bsxfun() if you want.

 B = reshape([A;A;A] + repmat([-1;0;1],1,size(A,2)),1,[]);

Thanks Adam :), at first sight the question seemed to be unclear actually.
