336.0000
365.0000
166.0000 求出了点的坐标，怎么把它们画在一张图上，以点的形式，不是曲线，看出大致点的分布情况
那可以调整坐标轴的长度么，总觉得有点变形，和原图片的点对不上

Answer 1

使用plot(x,y,'*')

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

For example, PLOT(X,Y,'c+:') plots a cyan dotted line with a plus
at each data point; PLOT(X,Y,'bd') plots blue diamond at each data
point but does not draw any line.

祝你学习愉快！
