Hello,

I am new in Matlab and I don't know how to add an element to the next element in my vector (i+1). I tried several loops but couldn't make them work.

Here is an example:

A=[2 2 2 2];

I want "B" to be:

B=[2 4 6 8]

My vectors are actually thousands long, so I need a method to easily create such kind of "continuous" vectors. I will really appreciate any help about this.
