Matlab-多曲面畫法和多ColorMap表示

爲了避免自己忘記，寫個筆記吧。

先上效果圖：

 

然後是代碼，主要是爲了自己不忘記，而且自己是新手，所以沒有遵守代碼規範，有問題評論問我吧。

clc;
x_1 = 0.01:0.01:0.99;
x_2 = 1.01:0.01:10.0;
y = 0.01:0.01:0.99;
%五個曲面，定義五組顏色
colormap([parula(32);hot(32);cool(32);winter(32);pink(32)]);
%z1-z5代表五個曲面

% z1
%歸一化 把數據用[1,32]之間的數據表示，32是上面定義的顏色數
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
%歸一化 把數據用[33,64]之間的數據表示
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
%歸一化 把數據用[65,96]之間的數據表示
num(5) = min(z3(:));
num(6) = max(z3(:));
c = min(32,round(31*(z3 - num(5))/(num(6) - num(5)))+1) + 64;
%END

% z4 
%歸一化 把數據用[97,128]之間的數據表示
num(7) = min(z4(:));
num(8) = max(z4(:));
c = min(32,round(31*(z4 - num(7))/(num(8) - num(7)))+1) + 96;
%END

% z5
%歸一化 把數據用[129,160]之間的數據表示
num(9) = min(z5(:));
num(10) = max(z5(:));
c = min(32,round(31*(z5 - num(9))/(num(10) - num(9)))+1) + 128;
