我想生成使用 matlab2tikz 创建的平滑曲面图。但是，如果我使用所需的文档，内存[shader = faceted interp]将从[shader = flat corner]34KB 增加到大约 3000 KB。
是否有可能使用更少的内存来生成插值表面颜色？
这是由 matlab2tikz 生成的 TikZ 代码：

答案1
这pgfplots 手册在第 139 页对此发出警告：
原则上，这个想法本身并没有什么问题，而且看起来也不错——但它会大大扩大生成的 PDF 文档，并且可能需要很长时间才能渲染
后来，它给出了一种解决方法：
对于正交图（如 view={0}{90}），如果使用两个单独的 \addplot 命令，可以以较低的成本获得分面插值的效果：一个使用 surf，一个使用 mesh。请谨慎处理此选择。
使用这个技巧，我制作了下面的图表，它只有 41K（使用 pdflatex 生成的 pdf，standalone类）：
为此，我将您的表格数据复制到单独的data.txt文件中，删除\\每行末尾的，然后在文档中输入以下命令：
\pgfplotstableread{data.txt}\data
这使我能够重复使用两个图（表面和网格）的数据：
\begin{tikzpicture}
\begin{axis}[% options omitted
]
\addplot3[surf,
shader=interp, colormap={mymap}{[1pt] % long colormap omitted
}, mesh/rows=20]
table {\data};
\addplot3[mesh,mesh/rows=20, color=black]
table {\data};
\end{axis}
\end{tikzpicture}
请注意，我删除了point meta=\thisrow{c}，因为当从外部文件加载表时它不起作用，而且我不知道这个选项的含义（我不是 pgfplots 的常规用户）。
答案2
为了直接从 Matlab 获取所示的解决方案，我现在分割了图。
Matlab代码：
figure
surf (xData, yData, zData, 'EdgeColor', 'none', 'FaceColor', 'interp')
hold on
mesh (xData, yData, zData, 'EdgeColor', 'black', 'FaceColor', 'none')
