My paper having 3 different authors with a common affiliation. I am trying to center the third author position using centering command but it's not working. Its IEEE conference latex version.I used below script:

    begin{document}



title{Paper Title*\

{footnotesize textsuperscript{*}Note: Sub-titles are not captured in Xplore and

should not be used}

thanks{Identify applicable funding agency here. If none, delete this.}

}

author{IEEEauthorblockN{textsuperscript{}Ali}

IEEEauthorblockA{textit{School of Engineering and Information Technology } \

textit{The University of New South Wales (UNSW) }\

}

and

IEEEauthorblockN{textsuperscript{}Abbass}

IEEEauthorblockA{textit{School of Engineering and Information Technology} \

textit{The University of New South Wales (UNSW) }\

}

and

centering

IEEEauthorblockN{textsuperscript{} sayed}

IEEEauthorblockA{textit{School of Engineering and Information Technology} \

textit{The University of New South Wales }\

}



}

maketitle

end{document}

For over three affiliations, or if they all won't fit within the width of the page, use this alternative format:
