[求助] matlab中等值线的标注

  [X,Y] = meshgrid(-2:.2:2,-2:.2:3);   
Z = X.*exp(-X.^2-Y.^2);  
[C,h] = contour(X,Y,Z);     
set(h,'ShowText','on','TextStep',get(h,'LevelStep')*2)

  [C,h] = contour(X,Y,Z,20);

[C,h] = contour(X,Y,Z,v);

经过测试 设置了线条数目后再设置step属性便会无效
但是可以提供一个解决该问题的思路
请看程序：
clear all;clc;
= meshgrid(-2:.2:2,-2:.2:3);   
Z = X.*exp(-X.^2-Y.^2);  
= contour(X,Y,Z,10);     ...

clear all;clc;
[X,Y] = meshgrid(-2:.2:2,-2:.2:3);   
Z = X.*exp(-X.^2-Y.^2);  
[C,h] = contour(X,Y,Z,10);   
set(h,'ShowText','off')
hold on;
[C1,h1] = contour(X,Y,Z,5);
set(h1,'ShowText','on')
