# Behaviour of an expression

#### Akibarika

I have an expression with piecewise functions. the code looks like:

Code:
function a()
%some constants here

f = 0:0.001:20;
r1 = 0.05;
p = something-f.*(something/something);
for i=1:100
r1= R(p);
end
for i=1:100
r1 = R(P);
y1(k,:) = r1;
end
y1=sort(y1)
plot(f,y1,'k.','MarkerSize',1)
xlabel('f')
ylabel('r1');
set(gca,'xlim',[0 20]);

%piecewise functions here
function r = R(P)
r = NaN(size(P));
r(P<=0) = sqrt((somthing)*(1-P(P<=0)/something).^-2);
r(P>0) = sqrt((somthing)-(somthing)*(1-P(P>0)/somthing).^-5);
end

end
My friend said the behaviour will be like the logistic map. but after printing, I found it just looks like a curve.

Kind Regards
