这是我的问题。我有一些Excel格式的数据组织在x，y，z值的三列中。我想在Matlab的x-y平面上创建2d等高线图。 “ x”和“ y”是形状的坐标，“ z”是形状的不同节点的应力。任何列都有6k行。这是我的Excel专栏的一部分：

我有两个不同的代码。第一个是：
filename = 'node_coordinate.xlsx';
sheet = 1;
XRange = 'B2:B6194';
YRange = 'C2:C6194';
ZRange = 'I2:I6194';
x = xlsread(filename,sheet,XRange);
y = xlsread(filename,sheet,YRange);
z = xlsread(filename,sheet,ZRange);
[X, Y] = meshgrid(sort(x), sort(y));
Z = griddata(x, y, z, X, Y);
figure(8)
surf(X,Y,Z)
contourf(X,Y,Z)
colormap cool
colorbar('location','EastOutside')
beta =0.4;
brighten(beta);
axis square
我希望是这样的：[https://i.stack.imgur.com/hVNYB.png][1] 但我明白了：[{https://i.stack.imgur.com/NWlTo.png][1]
我的第二个代码是：

figure(1)
p_h=plot3(x,z,y,'o');grid
rangeZ=floor(min(z)):3:ceil(max(z)); %3 is the spacing I have chosen.

[X,Y] = meshgrid(x,y);

但是它要花费很多时间，并使matlab变得“忙碌”几个小时，所以我认为那不是正确的代码。 有人帮忙吗？ 预先感谢，问候。
答案 0 :(得分：0)
您的示例非常相似...
我不确定发生了什么，但有一些想法：
X和Y将包含许多重复点。要纠正该错误：
%TODO: you'll need to define rangeY instead of rangeZ
rangeX=floor(min(x)):0.5:ceil(max(x));
[X,Y] = meshgrid(rangeX,rangeY);
scatter进行调试。 示例代码：
%For the original data:
sz = 5; %size of point, user preference
scatter(x,y,sz,z,'filled')
%For the new data
scatter(X(:),Y(:),sz,Z(:),'filled')
正如第一点所提到的，第二个示例使用z，而应使用y ...
根据您的示例，您似乎希望griddata在不存在数据的区域内插值。我认为griddata在指定的点平滑，而不是在指定的点锚定，这可能会导致数据中的孔出现一些问题...
这些东西都不能真正解决获得所需轮廓的问题。如果实际上已经对数据进行了均匀采样（在网格中），但是您只缺少点（即您有某种稀疏矩阵），则可以创建一个适当大小的矩阵并填充您拥有的点。我不完全确定该怎么做，但这应该相对容易。为了使这个示例更清楚，请考虑您具有以下数据点：
x = [0.5 0.5 1 ];
y = [0.6 1.2 0.6];
z = [4 5 6];
然后，您可以将其视为类似于2x2矩阵，其中缺少一个/空的点，因此您的最终矩阵可能是：
Z = [4 6; ...
5 NaN]; %<= missing point since no x = 1, y = 1.2 pair
X = [0.5 1];
Y = [0.6 1.2];
这是因为将0.5和1分别作为X的索引1和2，以及将0.6和1.2分别作为Y的索引1和2。
