В приведенном ниже коде, если я скомпилирую его с помощью WinEdt и XeLaTeX, мое уравнение получится таким:
Однако, когда я использую PFDLaTeX для компиляции, уравнение получается правильным:
Как правильно отобразить уравнение с помощью XeLaTeX?
Вот код:
\documentclass{book}
\usepackage{amsmath,amsfonts,amssymb,amsthm, bm}
\usepackage{tikz}
\usetikzlibrary{tikzmark,calc,arrows,shapes,fit,decorations.pathreplacing,pgfplots.groupplots, matrix}
\tikzset{every picture/.style={remember picture}}
\begin{document}
\begin{equation}
\tikz{\node{\subnode{d4}{$\hat{{\theta}}_{BLU}(k+1)$} = \subnode{d5}{$\hat{{\theta}}_{BLU}(k)$} + \subnode{d6} {$\mathbf{K_{B}}(k+1)$}\subnode{d7}{$\big(\underbrace{z(k+1)-\mathbf{h}'(k+1)\hat{{\theta}}_{BLU}(k)}\big)$}};}
\end{equation}
\begin{tikzpicture}[remember picture,overlay]
\draw[blue,thick,->] (d4) to [in=90,out=245] + (245:2.2cm) node[anchor=north,text = black] {current estimate};
\draw[blue,thick,->] (d5) to [in=90,out=265] +(255:1.1cm) node[anchor=north,text = black] {previous estimate};
\draw[blue,thick,->] (d6) to [in=90,out=265] +(279:2.0cm) node[anchor=north,text = black,text width=3cm,align=center]
{(gain)\\ The weight\\ of the adjustment};
\draw[blue,thick,->] (d7) to [in=90,out=265] +(335:1.6cm) node[anchor=north,text = black,text width=4cm,align=center]
{residual prediction\\ how far the previous\\ estimation from the \\ current measurement};
\end{tikzpicture}
\end{document}
решение1
Я не совсем понимаю ваш подход, но вот как бы я это сделал. Это работает с xelatex и pdflatex.
Главное — определить макрос.
\tikznode[..options..]{..label..}{..contents..}
чтобы отметить содержимое, откуда исходят стрелки. Чтобы добавить стрелки и текст, используйте
\begin{tikzpicture}[remember picture,overlay]
... tikz code using the labels defined by \tikznode ...
\end{tikzpicture}
Определите команду \tikznode
в преамбуле как
\usepackage{tikz}
\newcommand\tikznode[3][]%
{\tikz[remember picture,baseline=(#2.base)]
\node[minimum size=0pt,inner sep=0pt,#1](#2){#3};%
}

Результат такой же, как и во втором снимке OP.
