Hi all,
I have a question about the below code :
1 : . 5 : 10
Would you please explain what does it do?
Actually the '.5' between 1 and 10 confused me, I run it in MATLAB It
gave me a row vector with 19 columns, I don't now what's its
functionality.
Thanks in Advance.
Sophia.

Oh. You never read them, or any of the help documents? Is
that why you are asking the most basic question possible,
one that will be covered almost immediately?
Really, you need to read the help. Otherwise, you will be
asking questions for every single function and command
in matlab.
Next, learn to experiment. Try things in matlab, in the
command window. See what they do, and see how that
relates to what you tried.
If you honestly did this and cannot imagine what that
expression does in matlab, then you really desperately do
need to read the tutorials.

Gosh, I thought this was quite clearly covered in the tutorials.

Agreed, but specifically for this introductory problem, try
