Plotting multiple equations in one plot
显示 更早的评论
I am trying to create my own plot of the following and can't seem to get it right. I can't figure out how to plot the equations for both r and 1/l, I only seem to plot an equation for either r or 1/l.
I used 'linspace' to get an even 100 points for both r and 1/l.
The equations I'm trying to plot are as follows:
V/c = ln(l) - (1/r)*(1-1/l), for V/c = 0.5 & 1
nmax + 1 = r*l, for nmax+1 = 8 & 4
tb/Isp = (1/r)*(1-1/l), for tb/Isp = 1 & 0.5
Any help would be greatly appreciated!

Can you post your work so far? Are you using "hold on" to let the plot take a second set of data?

You would use
plot(1./l, r)
The vectors for l and r must be the same length. You cannot have a value of zero in l when you calculate 1/l of course.

L=.01:.01:1;
count=1;
for v=[.5 1]
r(count,:)=(1-L)./(log(1./L)-v);
count=count+1;
end
for n=[8 4]
r(count,:)=n*L;
count=count+1;
end
for tb=[1 .5]
r(count,:)=(1-L)/tb;
count=count+1;
end
plot(L,r);
