c=[1 -12 24 -48]
croots=roots(c)
Use the if - elseif construct to plot the 1st root as follows: if
the root is less than 3 or greater than 5, plot the root as red + with
size 32; if the root is greater than 3 and less than 5, plot the root
as a blue square size 32.

Check the demo example.

for i = 1:10
x = rand ;
if x < 0.5
plot(i,x,'*r')
else
plot(i,x,'*b')
