How to create a vector of increasing and decreasing increments with linspace?

I need to create a vector b = 1 2 3 4 5 6 7 8 9 10 9 8 7 6 5 4 3 2 1 (19 elements) using linspace function. How would I create this with only one command?

Why not just

b = [1:10,9:-1:1]

?

This sounds like a strange requirement. What is the full text of this homework assignment?

[Rahul Kumar]

 b = [linspace(1,10,10) linspace(9,1,9)] 

[John D'Errico]

Clearly homework, because requiring the use of linspace is artificial. And there is no need to use linspace either. You don't even need to use brackets, if you want to be tricky. For example...

10 - abs(-9:9)

Or, perhaps this one?

1 + abs(mod(0:18,10) - 8*floor((0:18)/10))

Not at all hard to find multiple ways to do this homework problem. That linspace was not used in these ways seems irrelevant. And really, who needs linspace anyway? Unless it is for homework.
