Matlab2tikz 和对齐：我需要帮助

我使用 matlab2tikz 将两个 matlab 图像转换为 .tex 文件，第一个图像生成了以下代码：

现在，我成功地按照以下说明在我的 Latex 主程序中显示了这两个图表：

\begin{figure}[h]
    \centering
    \input{Error_uniform_53}
    \caption{Caption 1}
    \label{fig:1}
\end{figure}

\begin{figure}[h]
    \centering
    \input{Error_uniform_10}
    \caption{Caption 2}
    \label{fig:2}
\end{figure}

Error_uniform_53第一个 .tex 文件的名称在哪里Error_uniform_10，第二个 .tex 文件的名称是什么。我想将这两个图表并排放置，我已经尝试使用 subfigure，但似乎不起作用，可能是因为 tikzpiucture。有人能帮帮我吗？
我在这里留下一个 MWE（记住我给包含图片的 .tex 文件起的名字）：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[italian]{babel}
\usepackage{graphicx, subfigure}
\usepackage{amsmath, amsfonts, amssymb, amsthm}
\usepackage{caption}
\usepackage{float}
\usepackage{tikz}
\usetikzlibrary{plotmarks}
\usepackage{tikz-cd}
\usepackage{pgfplots} 
\pgfplotsset{compat=newest}

\begin{document}

\begin{figure}[h]
    \centering
    \input{Error_uniform_53}
    \caption{Caption 1}
    \label{fig:1}
\end{figure}

\begin{figure}[h]
    \centering
    \input{Error_uniform_10}
    \caption{Caption 2}
    \label{fig:2}
\end{figure}

\end{document}

答案1

好的，这里有一种方法可以做到。恐怕您需要重新制作生成的tikz图片，因为如果不产生布局问题，您就无法\input直接使用它们。即首先注释掉下面提到的部分。

我们来看一下。

前言

和你一起工作真是……令人讨厌。因此，这个在下面给出的上下文中工作，其中 ams-packages 仅适用于在内部创建的标题pgfplots：

\documentclass[10pt,a4paper]{article}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\usepackage{amsmath, amsfonts, amssymb, amsthm}
\usepackage{caption}

需要包caption，因为 minipage 不使用浮动环境。使用方式如下：

\captionof{figure}{Cap 2}\label{fig:2}

使用小页面

与@Zarko 提出的类似，结构如下：

 \begin{minipage}{7cm}% ~~~ minipage 1 ~~~~~~~~~~
 ... // first drawing
 \end{minipage}
 \hfill
 \begin{minipage}{7cm}% ~~~ minipage 2 ~~~~~~~~~~
 ... // second drawing
 \end{minipage}

现在，我对minipage环境的使用肯定可以得到改善，而这个环境是有效的。

让我们来看看戏剧性的一幕，生成的两个文件

简而言之，该代码在您想要的上下文中带来了一些不愉快的惊喜，尽管它们单独运行良好。因此，为了消除\input它们，您需要稍微注释掉它们。下面的代码只是复制了两个部分，以更好地显示哪些是过时的，甚至会造成麻烦。

对布局、比例、定位进行毫无意义且具有反作用的改变；只需将其删除：

        %width=4.521in,% <<< all these give unwanted shifts and scalings
        %height=3.566in,
        %at={(0.758in,0.481in)},
        %scale only axis,

最后的这部分很疯狂，导致了更难以定位的问题；所以，摆脱它：

        %\begin{axis}[% <<< these are simply not good
        %width=5.833in,
        %height=4.375in,
        %at={(0in,0in)},
        %scale only axis,
        %xmin=0,
        %xmax=1,
        %ymin=0,
        %ymax=1,
        %axis line style={draw=none},
        %ticks=none,
        %axis x line*=bottom,
        %axis y line*=left
        %]
        %\end{axis}

请检查每个生成的图表开头的这一行，您必须添加或修改它以进行缩放：

\begin{tikzpicture}[scale=.8,transform shape]

将此缩放因子与您用于小页面的宽度平衡。
