4（子）子图 + 1 子图并排

Question

这是我尝试过的。为了可重复性，我使用了[demo]。我希望右侧的图能够整齐地放置，并且与左侧的图高度相同。

\documentclass{article}
\usepackage{caption,subcaption}
\usepackage[demo]{graphicx} % demo is just for the example

\begin{document}
\begin{figure}
\centering
\begin{subfigure}[b]{.45\textwidth}
\includegraphics[width=\textwidth,height=5cm]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/Elbow.pdf}
%\caption{A tall figure}
\end{subfigure}\qquad
\begin{subfigure}[b]{.45\textwidth}
    \begin{subfigure}[b]{.45\textwidth}
        \includegraphics[width=\textwidth]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
        %\caption{}\label{}
    \end{subfigure}
    \begin{subfigure}[b]{.45\textwidth}
        \includegraphics[width=\textwidth]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
        %\caption{}\label{}
    \end{subfigure}

        %\caption{}\label{}

        %\caption{}\label{}
    \end{subfigure}
\end{subfigure}\qquad

像这样？

\documentclass{article}
\usepackage{caption,subcaption}
\usepackage[demo]{graphicx}   
\usepackage{tabularx}

\begin{document}
    \begin{figure}
    \centering
    \begin{tabularx}{\linewidth}{XX}
\begin{subfigure}{\linewidth}
\includegraphics[width=\linewidth,height=5cm]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/Elbow.pdf}
\caption{A tall figure}
\end{subfigure}
    &
\begin{subfigure}{\linewidth}
    \begin{subfigure}{0.48\linewidth}
        \includegraphics[width=\textwidth]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
        \caption{}\label{}
    \end{subfigure}\hfill
    \begin{subfigure}{0.48\linewidth}
        \includegraphics[width=\linewidth]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
        \caption{}\label{}
    \end{subfigure}

    \begin{subfigure}{0.48\linewidth}
        \includegraphics[width=\linewidth]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
        \caption{}\label{}
    \end{subfigure}\hfill
    \begin{subfigure}{0.48\linewidth}
        \includegraphics[width=\linewidth]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
        \caption{}\label{}
    \end{subfigure}
\end{subfigure}
\end{tabularx}

\end{figure}
\end{document}

或者您希望让第一个子图像的高度等于右列中两个子图像的高度，就像我在给出的链接的评论中所做的那样？

根据上面@Zarko 的评论，我对其进行了修改以适合我的问题：

\documentclass{article}
\usepackage{caption,subcaption}
\usepackage[demo]{graphicx}   
\usepackage{tabularx}

\begin{document}
    \begin{figure}
        \centering
        \begin{tabularx}{\linewidth}{XX}
            \begin{subfigure}{\linewidth}
                \includegraphics[width=\linewidth,height=5cm]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/Elbow.pdf}
                %\caption{A tall figure}
            \end{subfigure}
            &
            \begin{subfigure}{\linewidth}
                \begin{subfigure}{0.48\linewidth}
                    \includegraphics[width=\textwidth, height=2.5cm]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
                    %\caption{}\label{}
                \end{subfigure}\hfill
                \begin{subfigure}{0.48\linewidth}
                    \includegraphics[width=\linewidth, height=2.5cm]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
                    %\caption{}\label{}
                \end{subfigure}

                \begin{subfigure}{0.48\linewidth}
                    \includegraphics[width=\linewidth, height=2.5cm]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
                    %\caption{}\label{}
                \end{subfigure}\hfill
                \begin{subfigure}{0.48\linewidth}
                    \includegraphics[width=\linewidth, height=2.5cm]{/home/ayan/Programs/David_Parkinson/Reduced_Reshaped/ML_Data/BIN_1/KMeans_Cluster_1_hist.pdf}
                    %\caption{}\label{}
                \end{subfigure}
            \end{subfigure}
        \end{tabularx}
