Question

Having trouble with this MATLAB script, can someone help?

I'm trying to make values of x1 and x2 greater than -0.5 and less than 0.5 automatically become 1 so that the graph is more like a square wave or a castle wall. Thank you!

My script:

t=0:0.01:360;

x1=sind(3*t);

x2=cosd(3*t);

if x1 < 0.5

x1 = 1;

plot(t,1,'*');

end

if x1 > -0.5

x1 = 1;

plot(t,1,'o');

end

while x2 < 0.5

x2 = 1;

plot(t,1,'*');

end

while x2 > -0.5

x2 = 1;

plot(t,1,'o');

end

plot(t,x1,'*');

plot(t,x2,'o');

subplot(211);plot(t,x1); axis([0 360 -1.5 1.5])

title('t. vs. Sine'); xlabel('time');ylabel('Sine Graph')

grid on

subplot(212);plot(t,x2); axis([0 360 -1.5 1.5])

title('t. vs. Cosine'); xlabel('time');ylabel('Cosine Graph')

grid on
