How to shift a vector using 'for' loop

Question

0 投票

Dear members

Firstly,I have many vectors for example (V1, V2, V3, V4 ...) of M length.

How can I use 'for' loop to obtain firstly [V1 V2] then [V2 V3] then [V3 V4], [V4 V5] ... etc. It means I shift the previous vector each time.

Thank you.

"I have many vectors for example (V1, V2, V3, V4 ...)"

How did you get them all into the workspace? Did you name them all by hand?

No, I found them using many operations not just by hand

Store all of the vectors in one cell array (which they should be anyway):

C = {V1, V2, V3, V4 ...};

then all you need is this loop:

for k = 2:numel(C)
    [C{k-1},C{k}]
end

or even just this:

for k = 2:numel(C)
    [C{k-1:k}] % comma-separated list and concatenation
end
