Figura tikz en blanco en un archivo pdf.

Esta podría ser una publicación muy problemática, lo siento de antemano.

Estoy intentando dibujar una figura usando tikz para un manuscrito y cuando lo usé, la primera vez funcionó muy bien. Pero ahora agregué algunas funciones en mi archivo de "comandos" y desde entonces, cuando ejecuto mi documento: no se detecta ningún error, pero la figura simplemente no aparece: en cambio, hay una página completamente en blanco y no entiendo por qué. ...

Aquí está mi código reducido que muestra el problema:

\documentclass[a4paper,11pt,twoside]{book}

\include{formatAndDefs}

\begin{document}
\pagenumbering{roman}

\setcounter{page}{0}
\bibliographystyle{StyleThese}
\begin{vcenterpage}
\noindent\rule[2pt]{\textwidth}{0.5pt}

\begin{tikzpicture}[
scale = 0.675
]
\fill[cyan!25] plot[domain=0:8, samples=100] (\x, {gauss(\x)})|- (0,0);
\draw[very thick, orange!60]  plot[domain=0:9.5, samples=100] (\x, {gauss(\x)});
\fill[gray!25] (0,-0.5) -- (0,0) -- (9.5,0) -- (9.5,-0.5) -- (0,-0.5);
\fill[pattern = north east lines] (-0.5,-0.5) -- (0,-0.5) -- (0,4.5) -- (-0.5,4.5) -- (-0.5,-0.5);
\draw[red, dashed, thick, Stealth-Stealth] (-0.25,0) --node[fill=white,scale=0.75]{$h$} (-0.25,{gauss(0)});
\draw[red, dashed, thick, Stealth-Stealth] (0,-0.225) --node[fill=gray!25,scale=0.55]{$R$} (7,-0.27);
\draw[black, dashed, thick, Stealth-Stealth] (0,{gauss(0)}) --node[above,scale=0.65]{$L$} (7,0);
\node[below left, scale = 0.85] at (9,3) {$\boxed{\epsilon \approx \frac{L-R}{R}}$};
\end{tikzpicture}

\noindent\rule[2pt]{\textwidth}{0.5pt}
\end{vcenterpage}
\end{document}

El problema es que estoy obligado a compartir mi archivo de comandos personalizado... Ya que es importante para resolver el problema. La función creada se muestra en la sección "Algunas funciones gaussianas" del archivo.

El espacio puede importar. Tienes un espacio espurio en la definición de tu función Gauss:

\pgfmathdeclarefunction{gauss}{1}{ %<------- here is a space (matters)
    \pgfmathparse{3*exp(-(#1/3.85)^2)} %<---- here too (probably harmless)
}

Deberías cambiar eso a

\pgfmathdeclarefunction{gauss}{1}{%
    \pgfmathparse{3*exp(-(#1/3.85)^2)}}

Puedes ver lo que sucede si usas números diferentes para las muestras:

\documentclass[a4paper,11pt,twoside]{book}

\usepackage{tikz,xcolor,amsmath,amssymb}

\pgfmathdeclarefunction{gauss}{1}{
    \pgfmathparse{3*exp(-(#1/3.85)^2)}
}
\usetikzlibrary{patterns}
\usetikzlibrary{arrows.meta,patterns.meta}

\begin{document}
\foreach\samples in {10,20,...,100}{%
\fbox{\begin{tikzpicture}
%\fill[cyan!25] plot[domain=0:8, samples=100] (\x, {gauss(\x)})|- (0,0);
\draw[very thick, orange!60]  plot[domain=0:9.5, samples=\samples] (\x, {gauss(\x)});
\fill[gray!25] (0,-0.5) -- (0,0) -- (9.5,0) -- (9.5,-0.5) -- (0,-0.5);
\fill[pattern = north east lines] (-0.5,-0.5) -- (0,-0.5) -- (0,4.5) -- (-0.5,4.5) -- (-0.5,-0.5);
\draw[red, dashed, thick, Stealth-Stealth] (-0.25,0) --node[fill=white,scale=0.75]{$h$} (-0.25,{gauss(0)});
\draw[red, dashed, thick, Stealth-Stealth] (0,-0.225) --node[fill=gray!25,scale=0.55]{$R$} (7,-0.27);
\draw[black, dashed, thick, Stealth-Stealth] (0,{gauss(0)}) --node[above,scale=0.65]{$L$} (7,0);
\node[below left, scale = 0.85] at (9,3) {$\boxed{\epsilon \approx \frac{L-R}{R}}$};
\end{tikzpicture}}\par}
\end{document}

Los espacios se acumulan y sacan tu imagen de la página:

Demasiado largo para comentar, el ejemplo puede reducirse a

Las dos primeras líneas de la imagen hacen que el contenido desaparezca. Aunque no sé por qué.

\documentclass[a4paper,11pt,twoside]{book}

\usepackage{tikz,xcolor,amsmath,amssymb}

\pgfmathdeclarefunction{gauss}{1}{
    \pgfmathparse{3*exp(-(#1/3.85)^2)}
}
\usetikzlibrary{patterns}
\usetikzlibrary{arrows.meta,patterns.meta}

\begin{document}
\begin{tikzpicture}
\fill[cyan!25] plot[domain=0:8, samples=100] (\x, {gauss(\x)})|- (0,0);
\draw[very thick, orange!60]  plot[domain=0:9.5, samples=100] (\x, {gauss(\x)});
\fill[gray!25] (0,-0.5) -- (0,0) -- (9.5,0) -- (9.5,-0.5) -- (0,-0.5);
\fill[pattern = north east lines] (-0.5,-0.5) -- (0,-0.5) -- (0,4.5) -- (-0.5,4.5) -- (-0.5,-0.5);
\draw[red, dashed, thick, Stealth-Stealth] (-0.25,0) --node[fill=white,scale=0.75]{$h$} (-0.25,{gauss(0)});
\draw[red, dashed, thick, Stealth-Stealth] (0,-0.225) --node[fill=gray!25,scale=0.55]{$R$} (7,-0.27);
\draw[black, dashed, thick, Stealth-Stealth] (0,{gauss(0)}) --node[above,scale=0.65]{$L$} (7,0);
\node[below left, scale = 0.85] at (9,3) {$\boxed{\epsilon \approx \frac{L-R}{R}}$};
\end{tikzpicture}
\end{document}

Y por @hpekristiansen más abajo a esto:

\documentclass[tikz, border=1cm]{standalone}     
\pgfmathdeclarefunction{gauss}{1}{     
\pgfmathparse{3*exp(-(#1/3.85)^2)} } 
\begin{document} 
\begin{tikzpicture} 
\fill plot[samples=100] (\x, {gauss(\x)}); 
\draw (0,0) -- (1,1); 
\end{tikzpicture} 
\end{document}
