# $$\(f(x)$$\) double $$'s problem Here is one problem I encountered with in Converting Mathematica Notebook to TeX: https://mathematica.stackexchange.com/questions/25928/save-as-tex-fx-double-s-problem And I got some double \('s \(\(f(x)$$\)


Is this a problem of Mathematica? I do not know where else would generate some similar $$s And, if I cannot control Mathematica to generate single \(, how to change the \(\( to \( conveniently ? I sometimes use Find/Replace to remove that redundant \( in WinEdt • @percusse Is it possible to compile two \(\('s ((f(x)(( without errors, in (for example) WinEdt?

It will make your life sooo much easier!

My guess is the converter used to output ... for inline math and ... for display. Now \(...$$ is often to be preferred for inline, but the dispaly equivalent is $...$ not $$\(...$$\).

• @AndrewSwann aha, something similar, good point. Maybe that's the answer. Jun 28, 2013 at 12:51

We can change the definition of $$ and $$ so that they check whether they are followed by another occurrence of themselve and \@gobble that.
These leave the math-shifts $ and $$ as they are, meaning that LaTeX’s superior $/$ will be used. Though, it would be better to fix Mathematica’s bug … ## Code \documentclass{article} \makeatletter \let\orig@mo$$\let\orig@mc$$ % (choose one) % $$\( = display style \def\({\kernel@ifnextchar\({\expandafter$\@gobble}\orig@mo} \def$${\kernel@ifnextchar\){\expandafter$\@gobble}\orig@mc} % $$\( = inline math \def\({\kernel@ifnextchar\({\expandafter\orig@mo\@gobble}\orig@mo} \def$${\kernel@ifnextchar\){\expandafter\orig@mc\@gobble}\orig@mc} \makeatother \begin{document} inline \frac {x^2}{y} display$$ \frac {x^2}{y} $$inline $$\frac {x^2}{y}$$ display $$\( \frac {x^2}{y}$$\) \end{document}  Almost certainly this is a badly configured conversion wher einline math has changed from  to $$ which has had an accidental effect where  has changed to \(\(. Fixing the convertor would be best but if you go \let\( \let$$  Then $$ will act like  and aaa\(a=b$$bbbbaaa$$\(c=d$$\)bbbb  will work like aaaa=bbbbbaaa$$c=d$\$bbbb
