I saw this:
plot(x,y,'ro')
I checked the doc but didn't find it. What does 'ro' mean? Thanks.

READ THE HELP! The important part is here:
Various line types, plot symbols and colors may be obtained with
plot(X,Y,S) where S is a character string made from one element
from any or all the following 3 columns:
b blue . point - solid
g green o circle : dotted
r red x x-mark -. dashdot
c cyan + plus -- dashed
m magenta * star (none) no line
y yellow s square
k black d diamond
w white v triangle (down)
^ triangle (up)
< triangle (left)
> triangle (right)
p pentagram
h hexagram
r and o are both listed as doing something independent of each other.

Yes, you can string together one from each column in a single quoted string. You can leave one or two out if you want, so you can have up to three (or 4) characters in the string, like 'ro-', 'ro', 'b--', 'mx-.', etc.
