Hi.. all
As has been mentioned at title, I'd like to draw circle with two color.
For example, upper half circle is red color and lower half circle is blue color.
Which code can I use to draw this circle?
Thank you for reading my writing...
Have a nice day!

x=-1:0.01:1
y1=sqrt(1-x.^2)
plot(y1,'r')
hold on
plot(-y1,'b')
or more general
c=1+2j % circle centre
r=4 % radius
x=real(c)-r:0.01:real(c)+r
y1=sqrt(r^2-(x-real(c)).^2)+imag(c)
plot(x,y1,'r')
hold on
plot(x,-y1+2*imag(c),'b')
axis square
