[Tex/LaTex] How to draw a vertical line of desired length in equations.

math-moderulessymbols

I am writing a big formula where a vertical line is needed. Instead of $\vline$ or $|$ , does anyone know a way to draw this vertical line of desired length? The formula is something like

$$
E\Bigg[
F_{m-1}\Big( \text{some big contents} \Big) |\: \mathcal{F}_1
\Bigg]
$$

Thank you very much!

Well, if you are manually defining the size, as in the example you could just put a \Bigg| at the right place. Probably better would be using \left, \middle and \right.

By the way: You should prefer \[ and \] instead of double $$.

\[ E\left[ F_{m-1}\Big( \text{some big contents} \Big) \middle|\: \mathcal{F}_1 \right] \]

use multiples of \baselineskip and in tabulars/arrays \normalbaselineskip

\documentclass{scrartcl}
\usepackage{mathtools}

\begin{document}

\begin{spreadlines}{2\baselineskip}
  \begin{align*}
    \pi(\mu \mid x) &= \frac{\pi(\mu)\,\mathcal{L}(x \mid \mu)}{p(x)} \\[\normalbaselineskip]
                    &= \begin{dcases*}
                         \frac{(1-w)\phi(x)}{p(x)} & for \(\mu=0\) \\
                         \frac{w\gamma(\mu)\phi(x-\mu)}{p(x)} & for \(\mu \neq 0\).
                       \end{dcases*}
  \end{align*}
\end{spreadlines}

[Tex/LaTex] How to draw a horizontal line between middle of the page and one of the edges (in beamerposter)

Thanks to the hint from JLDiaz I managed to do it using tikz. Here are the sources for the solution:

\documentclass[final,hyperref={pdfpagelabels=false}]{beamer}

\usepackage[english]{babel}
\usepackage[latin1]{inputenc}
\usepackage[orientation=portrait,size=a0,scale=1.4,debug]{beamerposter}
\usepackage{lipsum}
\usepackage{tikz}
\usetikzlibrary{calc}

\newcommand{\lefthalfline}{
    \begin{tikzpicture}[remember picture, overlay,line width=2mm]
    \coordinate (A);
    \path let \p1 = (A), \p2 = (current page.center) in (\x2-0.5\paperwidth,\y1) edge (\x2,\y1);
    \end{tikzpicture}\\}

\newcommand{\righthalfline}{
    \begin{tikzpicture}[remember picture, overlay,line width=2mm]
    \coordinate (A);
    \path let \p1 = (A), \p2 = (current page.center) in (\x2+0.5\paperwidth,\y1) edge (\x2,\y1);
    \end{tikzpicture}\\}

\begin{document}
\begin{frame}
  \begin{beamercolorbox}[wd=\paperwidth]{headline}
    \centering\huge Headline and stuff\\
    \rule{.5\paperwidth}{2mm}\kern-1mm
    \smash{\vrule height 0pt depth \paperheight width 2mm}\kern-1mm
    \rule{.5\paperwidth}{2mm}%
  \end{beamercolorbox}

  \begin{columns}
   \begin{column}{0.01\textwidth}
   \end{column}
   \begin{column}{0.48\textwidth}
    \huge \lipsum[1]
    \lefthalfline
    End of part one
   \end{column}
   \begin{column}{0.02\textwidth}
   \end{column}
   \begin{column}{0.48\textwidth}
    \huge Start of part two\\
    \righthalfline
    \lipsum[2]
   \end{column}
   \begin{column}{0.01\textwidth}
   \end{column}
  \end{columns}
\end{frame}
\end{document}
