我之前曾成功使用过\addplot graphics。现在我在 Matlab 中有一个冲浪图，我将其导出为 png 和 pdf，我想将图像包含在内\addplot3 graphics。我发现了一些关于这个主题的问题这里，这里， 和这里，所有这些都没有帮助我。我尝试了几次从中得到一组正确的点pgfplotscsconversion，但我的图形要么看起来像第一个链接或者大小完全被搞乱了——无论我使用哪种格式。我按照第二个链接，这应该给出正确的图形大小，但轴框似乎太小（或图像太大）。这是我的 MWE：
\documentclass[a4paper,10pt]{scrartcl}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[3d box,xmin=0,xmax=1,ymin=0,ymax=1,zmin=1,zmax=3]
\addplot3
graphics [
points={
(0.42545,0.84598,3) => (165.418,269.808)
(0.62718,0.73739,3) => (221.628,273.02)
(0.36528,0.67204,1.8154) => (179.872,164.615)
(0.81564,0.23471,1) => (334.851,96.36)
}]
{../matlabout.png};
\end{axis}
\end{tikzpicture}
\end{document}
如果没有最小/最大值，看起来会更糟。我担心这与第三篇帖子，但我希望有一个解决方案，而无需手动摆弄......

答案1
如何使用matlab2tikz? 这一直是我处理这些事情的最佳选择。您可以像平常一样在 matlab 中创建绘图，然后将包下载matlab2tikz到当前工作目录，输入 >>matlab2tikz('filename.tex')，然后创建一个用tikz命令编写的文件。
例子
