I need matlab code of this graph according to these conditions;
if the r value is lower than r1 and above than 0 use the formula L1.
if the r value between r1 and r2 use the formula L2.
if the r value greater than r2 use the formula L3.
Would you help me please?

This is not your function, however it illustrates the ‘logical indexing’ approach to such problems:
f = @(x) (2-2*x).*(x <= 0) + (2+2*x).*(x>0);
t = linspace(-3, 3);
figure
plot(t, f(t))
grid
ylim([0 max(ylim)])
Run it and view the plot it produces.
It is not difficult to figure out how it works. Be inspired by it!
