Creating a sawtooth wave of width in Matlab

This code is short and summarized to create triangular wave in matlab

clc , clear all , close all
t = 0:1:100; % time
A = 1; % amplitude
f = 22.5; % frequency
W = 2; % width
y = A*sawtooth (2* pi*f*t,W);
stem(t,y)
axis ([0 100 -3 3])
xlabel ('Time in seconds ')
ylabel ('Amplitude ')
title ('Triangular Wave')
