How to get selected value in a vector ?

I have temperature data of about 120 days and I want to select temperature of 1,12,24,36,48,60,72,84,96,108 and 120th day, How to select it?

When I am trying by this

for x=1:12:120

it is taking for 1, 13, 25 and so on

if I take x==linspace(0,120,11)

but I dont have any value at 0 i.e 0th day dont exist, it starts frrom 1st day.

Pls Help

Answer 2

[Walter Roberson]

for x=[1,12:12:120]

More obscurely in some ways, less obscurely in others:

for x = max(1, 0:12:120)
