how do i plot a sawtooth graph without using the sawtooth function?

T = 10*(1/50);
Fs = 1000;
dt = 1/Fs;
t = 0:dt:T-dt;
x = sawtooth(2*pi*50*t);
plot(t,x)
grid on

i) Write a set of MATLAB commands for approximating the continuous-time periodic Sawtooth wave of amplitude 5 volts, fundamental frequency 20Hz,and duty cycle 0.5. Plot five cycles of this waveform. ii) Find out the fourier series of this waveform plotted in (i). (iii) Plot the equation of Fourier series to get the original waveform back.
I stumbled over this question and generated an own solution:
To generate a sawtooth with time period T, over a time signal t just use interp1:
xx = [0 T/2 T];
yy = [1 0 1];
y = interp1(xx, yy, mod(t, T));
