Jex - supported Latex (and Mathtype)

by David K. Levine

Jex expects latex fragments enclosed in brackets {} and treats $'s as \$'s

Macros that do not exist in standard Latex; Jex will always try to convert these to equivalent Latex macros before writing, so these should not ordinarily occur in Jex output

\leftgroup{} \rightgroup{} - groups of fence delimiters, for example \leftgroup{[} is equivalent to \left[

\overset{}{} - groups of embellishments set above, for example \overset{-}{a} is equivalent to \overline a

\underset{}{} - groups of embellishments set below, for example \underset{-}{a} is equivalent to \underline a

{} \overgroup{}{} - groups of horizontal division style delimiters, for example {a} \overgroup{-} {b} is equivalent to a \over b

\unicode{c-style-hex-string} - the unicode character refered to by hex-string

Treatment of functions

functions such as \log \sin and so forth are converted by Jex to \mathrm{log} \mathrm{sin}

Latex constructs supported in Jex

No non-mathematical constructs are supported, and support for some symbols are not yet implemented. When macros unknown to it are encountered, Jex will try to ignore them.

Supported

        \begin{align} \end{align}
        \begin{array} \end{array}
        &
        \\ recognized as an array delimiter, but comments are not supported
        \mathrm{}
        \, \: \; negative spaces are neither recognized nor implemented
        \left[{( \right]})
        \sqrt{}
        \over
        superscripts and subscripts
        upper and lower case greek alphabet
        named functions
        embellishments both narrow and wide and underline
        all the symbols I know about except those listed below

Not Supported

        under and overbraces
        \frac
       \root[]{}
        \begin{math} \begin{display} \begin{equation} and the corresponding \end and the abbreviations \( \[
            these are essentially meaningless in Jex but the parser needs to do a better job of ignoring them
