Cómo eliminar el encabezado del frontmatter

Question

Tengo un encabezado creado con fancyhdr. Se repite en todas las páginas, incluidas las secciones de Índice y Prefacio. Intenté usarlo \thispagestyle{empty}pero solo funciona en la primera página mientras necesito borrarlo en lafrontmatter

\documentclass[11pt]{book}
\usepackage{lipsum}
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\fancyhead[LE,RO]{\thepage}
\fancyhead[RE]{\nouppercase{\leftmark}}
\fancyhead[LO]{\nouppercase{\rightmark}}

\renewcommand\headrulewidth{1.5pt}
\makeatletter
\def\headrule{{\if@fancyplain\let\headrulewidth\plainheadrulewidth\fi
        \hrule\@height\headrulewidth\@width\headwidth
        \vskip 2pt% 2pt between lines
        \hrule\@height.5pt\@width\headwidth% lower line with .5pt line width
        \vskip-\headrulewidth
        \vskip-1.5pt}}
\makeatother

Answer 1

cambiar este

\thispagestyle{empty}

a

\pagestyle{empty}

e inserte \pagestyle{fancy} aquí

\mainmatter
\chapter{Ch1}

Ahora se verá como

\mainmatter
\pagestyle{fancy}
\chapter{Ch1}

Answer 2

¿Es esto lo que quieres? Al principio, solo hay el título del capítulo (Contenido/Prefacio), las páginas del primer capítulo y las páginas blancas tienen un estilo vacío (para todo el documento). Agregué la twosideopción y utilicé los paquetes emptypageand xpatchepara lograrlo.

\documentclass[11pt, twoside]{book}
\usepackage{lipsum}
\usepackage{fancyhdr}
\usepackage{xpatch, emptypage}%
 \pagestyle{fancy}
\fancyhf{}
\fancyhead[LE,RO]{\thepage}
\fancyhead[RE]{\nouppercase{\leftmark}}
\fancyhead[LO]{\nouppercase{\rightmark}}

\renewcommand\headrulewidth{1.5pt}
\makeatletter
\def\headrule{{\if@fancyplain\let\headrulewidth\plainheadrulewidth\fi
        \hrule\@height\headrulewidth\@width\headwidth
        \vskip 2pt% 2pt between lines
        \hrule\@height.5pt\@width\headwidth% lower line with .5pt line width
        \vskip-\headrulewidth
        \vskip-1.5pt}}
\makeatother
