I have to plot sawtooth with amplitude of 4 and freq(fs) of 30
I m solving like sine wave. kindly find mistakes..
t = 0:5:30;
a = 4;
x = a*sawtooth(t);
plot(t,x)
axis([0 30 0 4])

Now i ve generate this.
close all
T=6;
Fs=10000;
dt = 10/Fs;
t = 0:dt:T-dt;
x = sawtooth(2*pi*t);
t=t*5;
plot(t,x)
grid on
this close is very close, but again issue is on Amplitude.. i want amplitude=4

T = 6;
Fs = 1e3;
dt = 1/Fs;
t = 0:dt:T-dt;
a = 4;
x = a*sawtooth(2*pi*t);
t = t*5;
plot(t,x)
grid on
