Hello I want to have this steps (1,2,4,6,8).
How can I do it to be in the form of, for example:
n=5
n=1:2:((2*n)-2)

t = 1:5; steps = 3+(-53/12+(71/24+(-7/12+(1/24)*t).*t).*t).*t
I would suggest that you reconsider your task. It would, for example, have been much easier as
t = 1:5; steps = [1, (t(2:end)-1)*2]

You cannot get that.
You can use (t-1)*2 + (t==1) or other ways of making an exception for the first value, but the 1 entry cannot be handled with a plain increment.
Now, if you had wanted [1, 2, 4, 8] without the 6 then that would have been easy: t = 1:4; 2.^(t-1)
