MATLAB: Writing and plotting function with multiple conditions

Question

Imagine I have a function like this:

How can I write this function in matlab and plot it between 0 and 1? How can I also compute of this function?

I want to have something like f=@(x) my_func

Answer 1

One possibility:

f = @(x) 9/5*x*(0<=x & x<1/2)+9/5*(1-x)*(1/2<=x & x<=1);

e.g.

f(0.1)
ans =
    0.1800
>> f(0.75)
ans =
    0.4500
