how to make piecewise continuous function periodic?

Hi, I have written this code for a piecewise continuous function for

    f(x) = {2*sqrt(x) 0>=x>=1
           {3-x       1>=x>=3

I am unsure how to make the function periodic with period 3 for all x? the code is:

    f = @(x) ((2*sqrt(x)).*(and(0<=x,x<=1)) + (3-x).*(and(1<x,x<=3)));
    x=0:0.01:3;
    plot(x,f(x))

any help would be much appreciated! Thanks

Are you and ‘john’ classmates by any chance?

I cannot in good conscience help him and not help you. See: How to plot a piecewise periodic function? Please Help.

Of course I would certainly encourage you to Accept this duplicate Answer as well!
