I cannot put all of the plot into one window. How do I plot in 3D?
v=3E8;
f=760E12;
x=zeros(400);
y=zeros(400);
z=zeros(400);
xx=zeros(400);
yy=zeros(400);
for tstep=1:360
t=tstep*1e-4;
x(tstep)=v*t;
y(tstep)=v/f*cos(tstep*pi/180);
z(tstep)=v/f*sin(tstep*pi/180);
xx(tstep)=(x(t)-y(t)*cos(45*pi/180));
yy(tstep)=z(t)-y(t)*sin(45*pi/180);
hold on;
plot(xx(tstep),yy(tstep),'-b');
end;
hold off;

Can be achieved without loop also.
