matlab画图怎么设置线条类型和颜色

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
v triangle (down)
^ triangle (up)
< triangle (left)

p pentagram
h hexagram
2、假如设置颜色为红色，线条为+，直线，则为plot(x,y,'r+-')
