Matlab中的极坐标图

Question

I have multiple theta and rho stored as matrices in variable out . I want to plot all of them using polar function in Matlab R2015b.

I'm new to Matlab and so far I did this :

subplot(1,3,1)
polar(out(1),out(2),'*')
subplot(1,3,2)
polar(out(3),out(4),'*')
subplot(1,3,3)
polar(out(5),out(6),'*')

I've two questions:

How can I combine them into a single polar plot, ie one figure instead of three with '*' position intact ?

How can I remove the lower part of polar plot so that I can have a semicircle instead of full plot? Is it possible to customize polar plot labels like removing the degree labels?

Answer 1

1. • Use the commmand hold on (and get rid of the subplots) or
   • Plot everything together with polar(out(1:2:end),out(2:2:end),'*')

2. Use the ylim([-0.5 0]) command see this answer .
