Matlab-多曲面画法和多ColorMap表示

为了避免自己忘记，写个笔记吧。

先上效果图：

 

然后是代码，主要是为了自己不忘记，而且自己是新手，所以没有遵守代码规范，有问题评论问我吧。

clc;
x_1 = 0.01:0.01:0.99;
x_2 = 1.01:0.01:10.0;
y = 0.01:0.01:0.99;
%五个曲面，定义五组颜色
colormap([parula(32);hot(32);cool(32);winter(32);pink(32)]);
%z1-z5代表五个曲面

% z1
%归一化 把数据用[1,32]之间的数据表示，32是上面定义的颜色数
num(1) = min(z1(:));
num(2) = max(z1(:));
c = min(32,round(31*(z1 - num(1))/(num(2) - num(1)))+1);
%END 
h(1) = surf(x_1, y, z1(1:99,:)');
hold on;
h(2) = surf(x_2, y, z1(100:999,:)');
set(h(1),'CData',c(1:99,:)');
set(h(2),'CData',c(100:999,:)');

% z2
%归一化 把数据用[33,64]之间的数据表示
num(3) = min(z2(:));
num(4) = max(z2(:));
c = min(32,round(31*(z2 - num(3))/(num(4) - num(3)))+1) + 32;
%END

set(h(3),'CData',c(1:99,:)');
set(h(4),'CData',c(100:999,:)');

% z3
%归一化 把数据用[65,96]之间的数据表示
num(5) = min(z3(:));
num(6) = max(z3(:));
c = min(32,round(31*(z3 - num(5))/(num(6) - num(5)))+1) + 64;

% z4 
%归一化 把数据用[97,128]之间的数据表示
num(7) = min(z4(:));
num(8) = max(z4(:));
c = min(32,round(31*(z4 - num(7))/(num(8) - num(7)))+1) + 96;
%END

% z5
%归一化 把数据用[129,160]之间的数据表示
num(9) = min(z5(:));
num(10) = max(z5(:));
c = min(32,round(31*(z5 - num(9))/(num(10) - num(9)))+1) + 128;
