I am trying to create a matlab variable that correlates with a vector.

The given vector in my problem is v34= [1:100}. I have to create a MATLAB variable v1 that adds 9 to each one of its 100 elements and a MATLAB variable v2 that adds 3 to each of its odd elements. I have tried using start values and nElements but i keep on getting an error. Am i supposed to use nElements for this kind of problem?

Does 'odd elements' mean 'elements with odd index'?

e.g. v34(1),v34(3),v34(43) etc. are the odd elements which you want?

Answer 1

[John D'Errico]

What does 1:2:end do for you (inside the parens)? Thus

v34(1:2:end)

Think about how you might use this idea, adding 3 to the elements of interest.

As for adding 9, surely you can add 9 to the entire vector in a trivial way. TRY IT!

If you don't try things and see what happens, you won't learn.
