**contourf(x,y,z);%等高线图
colormap(gray);设定图形颜色
scatter(x,y,’o’);%绘制散点图
X=A(:,1); Y=A(:,2); Z=A(:,12);
[x,y,z]=griddata(X,Y,Z,linspace(min(X),max(X),200)’,linspace(min(Y),max(Y),200),’v4’);%利
用离散的地理坐标得到Zn的二元拟合连续函数,进行插值
mesh(x,y,z);shading flat%网格状的三维曲面图
surfl(x,y,z);shading flat%光滑的三维曲面图
colormap(”)%设定曲面颜色
gray,winter,flag,cool..
%给图形家标注
title(”) %图形标题
%二维的
gtext(‘标注内容’,’fontsize’,15);%任意位置的标注
xlabel(‘..’,”,..,”,..);
ylabel(‘..’,”,..,”,..);
%三维图形的标注
