Symbolic or numeric?

How would you do a Symbolic one?

Answer 1

[Asad (Mehrzad) Khoddam]

This is a sample of function that repeats the graph:

% initial x
x0=-1;
% period
T=4;
xp=linspace(x0,x0+T,201);
% function
yp=sin(sqrt(2+xp));
x=[];
y=[];
% repeat it 
for i=-3:2
   x=[x xp+T*i];
   y=[y yp];
end

plot(x,y)
