Me and my friend are trying to multiply the sawtooth wave form and sin wave together. could someone help us with this command below is a photo of the multisim file we are try to recreate in matlab.
x = sawtooth(2*pi*50*t);
x1 = sin(pi/4*t+pi/2);
z=x.*x1;

You just need to define a time array. This should work for you:
t = 0:pi/12:2*pi;
x = sawtooth(2*pi*50*t);
x1 = sin(pi/4*t+pi/2);
z=x.*x1;
plot(t,x,t,x1,t,z)
legend('sawtooth','sine wave','combined')
