Try this:

out = linspace(2, 20, 10)

of course

out = 2 : 2 : 21;

is a lot more straightforward.

Hi, I am trying to create force my matlab plot to use a step of 10 years and not automatically choose one, so the years start from 2000 to 2100. I want a uniform space 2000, 2010, 2020...2100. How can I do this?

By the way I already tried x = linspace (2000, 2100, 11)

That will do it. Another way is to use the colon operator:

>> x = linspace (2000, 2100, 11)
x =
        2000        2010        2020        2030        2040        2050        2060        2070        2080        2090        2100
>> x=2000:10:2100
x =
        2000        2010        2020        2030        2040        2050        2060        2070        2080        2090        2100

A = 0:2:21;

0:2:21 does not do what you asked since it includes 0 while you specifically asked that 0 not be included.
