我正在使用将 Matlab 绘制的图形包含到 LaTeX 中。我通常的工作流程如下:
- matlab中的脚本创建图形,
- 我在可视化图形编辑器中调整我发现需要调整的内容,
- 图形保存为.fig(用于将来修改)和.eps(用于包含在LaTeX中) ,
- 我将.eps文件转换为.pdf,
- PDF文件在LaTeX源代码中引用。
重点是:当我尝试在轴标签、图例、标题等中使用非 ASCII 字符(确切地说:波兰国家字符,例如“ą”、“ę”、“ś”、“ć”)编码时Matlab 图形编辑器运行良好,字符显示正常。导出到 .eps 后,它们都是错误的(例如:“Głębokość”变成“G³êbokoœæ”)。
是否有一种方法可以通过调整 Matlab 选项或更改我的工作流程来正确执行此操作?
注意:我发现导出到 .png 或其他非矢量格式可以正确处理字符编码,但我想避免这样做那样 - 我在问一种“保持矢量”的方法。直接导出到 .pdf 会产生与 .eps 相同的效果,例如,它会产生错误的结果。
附言。 Matlab是R2008a,.latex文件用pdflatex编译,.eps文件用epstopdf从MikTeX 2.9编译(均在Win7下)。
I am using including Matlab-drawn figures into LaTeX. My usual workflow is as following:
- Script in matlab creates figure(s),
- I tweak what I find needs to be tweaked in visual figure editor,
- Figure is saved as .fig (for future modification) and .eps (for including in LaTeX),
- I convert .eps files to .pdf,
- PDF files are referenced in LaTeX source code.
To the point: when I try to use in axis labels, legend, titles, etc. non-ASCII chars, (to be exact: Polish national chars e.g. 'ą', 'ę', 'ś', 'ć') encoding in Matlab figure editor is fine and characters display properly. After exporting to .eps, they are all wrong (example: "Głębokość" turns into "G³êbokoœæ").
Does there exist a way to do this properly, either by tuning Matlab options or changing my workflow?
Note: I found that export to .png or other non-vector formats handles character encoding properly, but I would like to avoid having to do that -- I'm asking for a way to "keep it vector". Export directly to .pdf produces the same effect as .eps, e.g. it is producing wrong results.
PS. Matlab is R2008a, .latex files are compiled with pdflatex, .eps files with epstopdf from MikTeX 2.9 (all under Win7).

你可以看看psfrag,这是我尝试时通常使用的在 LaTeX 中使用 Matlab 图形。基本上,您只需将标签放入 Matlab 中的图形中,然后用 LaTeX 文本替换这些标签。最大的好处是,这允许您在文本和图形中使用相同的符号。
编辑:在寻找 psfrag-URL 时,我找到了一个 Matlab 脚本来简化此操作:
LaPrint。
You could have a look at psfrag, that's what I usually use when I try to use Matlab figures in LaTeX. You basically put just tags into the figure in Matlab and replace those tags with LaTeX text afterwards. The biggest benefit is that this allows you to have identical symbols in text and figures.
Edit: when looking for the psfrag-URL, I found a Matlab script to simplify this:
LaPrint.
另一种可能的解决方案是使用 matlab2tikz。它创建一个 tikz/pgfplot 源文件,可以直接包含在您的 Latex 源中。这意味着它使用 LaTeX 的工具来渲染字体。您可以直接编辑生成的文件来调整标签等。不幸的是,它并不适用于所有 MATLAB 图形。
Another possible solution would be to use matlab2tikz. It creates a tikz/pgfplot source file that may be included directly by your latex source. This means that it uses LaTeX's facilities for font rendering. You may directly edit the generated file to tweak the labels and such. Unfortunately, it doesn't work for all MATLAB figures.
对于 latin1 字符集中的其他字符,请看:
我正在使用 pdflatex,因此 psfrag 不是一个选项,并且 pdfrack 似乎已损坏。
For other characters in latin1 charset, Look at:
I am using pdflatex, so psfrag is not an option, and pdfrack seems to be broken.
对于导出具有非 ASCII ISO-8859-1 字符的 Matlab 图形,在 Windows 上没有问题,但在具有 UTF-8 语言环境的 Linux 上,存在 Matlab 错误和 解决方法。这里的问题针对的是 ISO-8859-1 之外的字符,这比较棘手。这是我在相关问题上发布的解决方案。
如果所需的字符数小于 256(8 位格式)并且理想情况下采用标准编码集,则一种解决方案是:
例如,如果要导出波兰语文本,则需要将文件转换为 ISO-8859-2。这是使用Python(多平台)的实现:
另存为eps_lat2.py;然后运行命令
python eps_lat2.py file.eps
(其中file.eps是Matlab创建的eps),使用Latin-2编码创建file_latin2.eps。文件 ISOLatin2Encoding.ps 包含编码向量:这是另一个实现在使用 Bash 的 Linux 上:
另存为 eps_lat2;然后运行命令
sh eps_lat2 file.eps
使用 Latin-2 编码创建 file_latin2.eps。通过更改脚本中的编码向量和 iconv(或 codecs.open)参数,它可以轻松适应其他 8 位编码标准。
For exporting a Matlab figure with non-ASCII ISO-8859-1 characters, there is no problem on Windows, but on Linux with a UTF-8 locale there is a Matlab bug and a workaround. The question here targets characters that are not in ISO-8859-1, which is more tricky. Here is a solution that I posted on a related question.
If the number of characters needed is less than 256 (8-bit format) and ideally in a standard encoding set, then one solution is to:
For example, if you want to export Polish text, you need to convert the file into ISO-8859-2. Here is an implementation with Python (multi-platform):
saved as eps_lat2.py; then running the command
python eps_lat2.py file.eps
, where file.eps is the eps created by Matlab, creates file_latin2.eps with Latin-2 encoding. The file ISOLatin2Encoding.ps contains the encoding vector:Here is another implementation on Linux with Bash:
saved as eps_lat2; then running the command
sh eps_lat2 file.eps
creates file_latin2.eps with Latin-2 encoding.It can easily be adapted to other 8-bit encoding standards by changing the encoding vector and the iconv (or codecs.open) parameter in the script.
