Creating Anonymous Functions for Complex Functions

[matematikawan]

I normally create anonymous function in order to avoid creating extra m-file if the function is simple enough. For example if I want to integrate the function f(x)=x²+x, I just write a simple MATLAB script like

myfun=@(x) x.^2 + x;
quad(myfun,0,1)


But how do we create an anonymous function for the following function
$$f(x)=\left\{\begin{array}{ccc}x,&\mbox{ } 0 \leq x <1\\ 1-x, & \mbox{ } 1 \leq x <2\\ 0 , & \mbox{ elsewhere } \end{array}\right.$$

The function look simple to me and I know how to write a function m-file for it. But I want to avoid it. Is it possible to create an anonymous function for it?

Here you go.

f = @(x) x.*(0<=x & x<1) + (1-x).*(1<=x & x<=2);

Thanks a lot matonski. This is really
