[Tex/LaTex] Vertical Fourier and Laplace “club” symbols

Question

The trfsigns package provides macros for transformation signs, eg: \fourier and \laplace.

I need a vertical version of those symbols.

Answer 1

\documentclass[a4paper,oneside,12pt]{report}

\usepackage{trfsigns} % Transformation Symbol o---o \laplace and \Laplace

\usepackage[fleqn]{amsmath}

\newcommand{\vlaplace}[1][]{\mbox{\setlength{\unitlength}{0.1em}%
                            \begin{picture}(10,20)%
                              \put(3,2){\circle{4}}%
                              \put(3,4){\line(0,1){12}}%
                              \put(3,18){\circle*{4}}%
                              \put(10,7){#1}
                            \end{picture}%
                           }%
                     }%

\newcommand{\vLaplace}[1][]{\mbox{\setlength{\unitlength}{0.1em}%
                            \begin{picture}(10,20)%
                              \put(3,2){\circle*{4}}%
                              \put(3,4){\line(0,1){12}}%
                              \put(3,18){\circle{4}}%
                              \put(10,7){#1}
                            \end{picture}%
                           }%
                     }%

\[ s(t) = stuff \]

\[\vLaplace[Used Rule No. 1 from Table No. 7] \]
\[ s(t) = again \]
