I need to plot a function but am not sure how to break it into multiple intervals. For example: 1 for -1<t<3 and 2t for 3<=t<6.
I also need to plot two different functions on the same graph and need help getting them both on the same graph

I don't know if I understand your problem, but I think it is related to the way to program the following code:
t=-1:0.1:6;
y=(t<=3).*sin(t)+(t>3).*cos(t);
y(t==3)=NaN;
plot(t,y)
