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
