Text Formatting ⇒ a new kind of 'superscript'

[casperyc]

Hi all,

Code: Select all

$\mu_x^j$

looks fine here,

Code: Select all

$\mu_{x+s}^j$

does not really express as it should be.
is there a way to make the 'j' cetering to the 'x+s'?
so 'j' is actually 'above' '+' in this case?

just as if

Code: Select all

\mu_{\stackrel{j}{x+s}}

has shifted

Thanks.

Hi,

you could use something like the following:

Code: Select all

\documentclass{article}

\begin{document}

$\mu_{x+s}^{\phantom{x}j\phantom{s}}$

\end{document}

yes, that's exactly what i am using now.
however, if the subscript varies too much,
it is not confortable to use it.

e.g. for
\mu_{xxxx}^{j}

i might have to use '2.5' times of \phantom{x}?

Thanks.

Try this improved version:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\usepackage{ifthen}
\usepackage{calc}

\newlength\mylena
\newlength\mylenb
\newlength\mylenc
% syntax: \mysp{<base>}{<subscript>}{<superscript>}
\newcommand\mysp[3]{%
  \settowidth\mylena{$\scriptstyle _#2$}%
  \settowidth\mylenb{$\scriptstyle \sp{#3}$}%
  \ifthenelse{\mylena<\mylenb}
    {%
      \setlength\mylenc{\mylenb-\mylena}%
      #1_{\hbox{\hskip.5\mylenc$\scriptstyle #2$}}^{#3}%
    }
    {
      \setlength\mylenc{\mylena-\mylenb}
      #1_{#2}^{\hbox{\hskip.5\mylenc$\scriptstyle #3$}}%
    }%
}

\begin{document}

$\mysp{\mu}{xxxx}{j}$

$\mysp{\beta}{xxx}{j}$

$\mysp{\alpha}{x}{j}$

$\mysp{\mu}{x}{jjjj}$

$\mysp{\beta}{x}{jjj}$

$\mysp{\alpha}{x}{jj}$

\end{document}

\begin{document}

$\mysp{\mu}{xxxx}{j}$

$\mysp{\beta}{xxx}{j}$

$\mysp{\alpha}{x}{j}$

$\mysp{\mu}{x}{jjjj}$

$\mysp{\beta}{x}{jjj}$

$\mysp{\alpha}{x}{jj}$

\end{document}

Thanks!

That works perfect!
