我试图以八度为单位绘制附加数据。第1列是X值,第2列是Y值,最后是Z值。
我正在运行此脚本:
xVec = reshape(mat(:,1),25,9);
yVec = reshape(mat(:,2),25,9);
zVec = reshape(mat(:,3),25,9);
surf(xVec,yVec,zVec);
axis([0.15 0.85 0.15 0.85]);
set(gca, 'XTick',0.20:0.05:0.80);
set(gca, 'YTick',0.20:0.05:0.80);
但是我不断得到一个很难理解的不平整表面。这是为什么?我错过了什么?

嗯,据我所知,你的数据X值每15点变化一次,Y和Z也是如此。 看来你正在重塑不正确。
尝试对代码进行下一个非常小的更改:
xVec = reshape(data(:,1),15,15);
yVec = reshape(data(:,2),15,15);
zVec = reshape(data(:,3),15,15);
surf(xVec,yVec,zVec);
axis([0.15 0.85 0.15 0.85]);
set(gca, 'XTick',0.20:0.05:0.80);
set(gca, 'YTick',0.20:0.05:0.80);
输出:
答案 1 :(得分:1)
(这只适用于matlab,因此我不知道octav是否有任何不同,但我不这么认为。)
问题是冲浪需要一种非常特殊的输入格式,它不适用于矢量。
你想要的功能是griddata
,它可以在偶数网格上插入任何3D或4D输入数据(这将是所需的冲浪输入)。
它有点像这样:
xVec=mat(:,1);
yVec=mat(:,2);
zVec=mat(:,3);
gridpoints = 100;
[xi, yi] = meshgrid(linspace(min(xVec),max(xVec),gridpoints),linspace(min(xVec),max(xVec),gridpoints));
zi = griddata(xVec,yVec,zVec,xi,yi);
surf(xi,yi,zi);
