[Tex/LaTex] How to avoid uppercase function name while using Function

algorithmscapitalization

In LaTeX, I want to define a function in my algorithm, following is my code in case:

\begin{algorithm}[h]
   \begin{algorithmic}[1]
       \Function{BuildPolicySet}{PolicySet PS, CCR ccr}
            blabla..
       \EndFunction
   \end{algorithmc}
\end{algorithm}[h]

In the pdf I got

function BUILDPOLICYSET(PolicySet PS, CCR ccr)

Actually I don't need the function name being in uppercase.

What should I do if I want the function name in the pdf to be the same as in the LaTeX code?

The function name is set using a predefined \textproc, which is similar to \textsc, changing the shape to small-caps. Redefine this to be empty and things will turn back to normal:

enter image description here

\documentclass{article}
\usepackage{algpseudocode}% http://ctan.org/pkg/algorithmicx
\algrenewcommand\textproc{}% Used to be \textsc

\begin{document}
\begin{algorithmic}[1]
  \show\Function
  \Function{BuildPolicySet}{PolicySet PS, CCR ccr}
    \State blabla..
  \EndFunction
\end{algorithmic}
\end{document}

The IEEEtran's documentation suggests:

B. Algorithms

IEEE publications use the figure environment to contain algorithms that are not to be a part of the main text flow. Peter Williams’ and Rogerio Brito’s algorithmic.sty package [24] or Szász János’ algorithmicx.sty package [25] (the latter is designed to be more customizable than the former) may be of help in producing algorithm-like structures (although authors are of course free to use whatever LaTeX commands they are most comfortable with in this regard). However, do not use the floating algorithm environment of algorithm.sty (also by Williams and Brito) or algorithm2e.sty (by Christophe Fiorio) as the only floating structures IEEE uses are figures and tables. Furthermore, IEEEtran will not be in control of the (non-IEEE) caption style produced by the algorithm.sty or algorithm2e.sty float environments.

So, as suggested, do not use the algorithm floating environment; you can wrap your algorithm inside a figure (or figure*) environment (if a caption is required and the captions are to be IEEEtran compliant) and use the algorithmicx package ; something like this:

\documentclass{IEEEtran}
\usepackage{algpseudocode}

\begin{document}

\begin{figure}
\begin{algorithmic}[1]
\Procedure{Euclid}{$a,b$}\Comment{The g.c.d. of a and b}
\State $r\gets a\bmod b$
\While{$r\not=0$}\Comment{We have the answer if r is 0}
\State $a\gets b$
\State $b\gets r$
\State $r\gets a\bmod b$
\EndWhile\label{euclidendwhile}
\State \textbf{return} $b$\Comment{The gcd is b}
\EndProcedure
\end{algorithmic}
\caption{Euclid's algorithm}\label{euclid}
\end{figure}

\end{document}

enter image description here

If no caption is required, then simply don't use the figure environment.

[Tex/LaTex] Referring to function name in an algorithm

You can define a new command, say \funclabel for storing the function name. Then you can retrieve it with the usual \ref.

\documentclass{article}
\usepackage{amsmath,algorithm,algpseudocode}

\makeatletter
\renewcommand{\Function}[2]{%
  \csname ALG@cmd@\ALG@L @Function\endcsname{#1}{#2}%
  \def\jayden@currentfunction{#1}%
}
\newcommand{\funclabel}[1]{%
  \@bsphack
  \protected@write\@auxout{}{%
    \string\newlabel{#1}{{\jayden@currentfunction}{\thepage}}%
  }%
  \@esphack
}
\makeatother


\begin{document}
\begin{algorithm}
\caption{My Algo.}
\label{alg:myalgo}
\begin{algorithmic}[1]
\Function{CallA}{$a$} \funclabel{alg:a} \label{alg:a-line}
    \State \Call{CalcSquare}{$a$}
\EndFunction
\Statex
\Function{CalcSquare}{$b$} \funclabel{alg:b}
    \State \Return $b\times b$
\EndFunction
\end{algorithmic}
\end{algorithm}
The \ref{alg:a} function at line~\ref{alg:a-line} calls \ref{alg:b} inside.
\end{document}
