Hi Stefan,
Thank a lot for your help. The code you sent to me , it works perfectly but the header title still on the right hand side. I want it (Header title)in the center.
I use this commands in the preambule
Code: Select all
\usepackage{fancyhdr}
\pagestyle{fancy}
\lhead{}
\chead{}
%\rhead{}
\renewcommand{\headrulewidth}{0.4 pt}
And in each chapter i put this command
Code: Select all
\markboth{\MakeUppercase{\thechapter. Performance of New Approach}}{\thechapter. Performance of New Approach}
. This allow me to get the header "Performance of New Approach" for this chapter. But still on the right side.
I read the document you advise me but don't really understand much. So could you please try to help me one more time ?
Thanks in advance !
