MATLAB 怎么画有三个自变量函数的三维图答：举个例子，画G(x,y,z)=x*cos(y)+z*y+sin(x+z)=0的图形 clear;clc [x,y,z]=meshgrid(linspace(-2*pi,2*pi));G=@(x,y,z)x.*cos(y)+z.*y+sin(x+z);%记住用点运算 isosurface(x,y,z,G(x,y,z),0)
请教用Matlab如何得到三维图象中峰值点的答：peaks;h=get(gca,'children');a=get(h,'xData');b=get(h,'yData');c=get(h,'zData');max；[d,e]=max(max(c));[f,g]=max(max(c'));text(a(g,e),b(g,e),c(g,e),['max-value:',num2str(f)]);迈特莱博
matlab 画出点的分布图 圆圈内包含数字答：给你一个例子 x=[1,2,3,4,5,6];y=[3,5,2,5,3,6];z=['5','6','6','5','4','5'];h=scatter(x,y,'SizeData',200);for i=1:6 text(x(i),y(i),z(i));end 颜色也是可以变的
