i am not getting correct output for this sawtooth plot

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])

And no of periods , how much do you want?

[Attaullah Shafiq]

Amplitude 5, freq 30, per 5

I have done this ones, but now i dont get this again.

yea i get this, but i ve problem using Amplitude..

[Attaullah Shafiq]

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

[Attaullah Shafiq]

Now Its done now

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

thank u...

how i set axis for this

axis([0 30 0 4])

but this is not aplly clearly
