Matlab function

  1. Oct 29, 2009 #1
    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
    [tex]
    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.
    [/tex]

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