Dear all,
The LaTeX {case} macro doesn't seem to work in Xwiki 2.0 with the default LaTeX renderer.
Try these two examples to reproduce it and compare with http://en.wikipedia.org/wiki/Math_markup#Examples_2: [XWIKI CODE STARTS HERE]
=== Continuation and cases=== This example from wikipedia doesn't seem to work: {{formula fontSize="normal"}}f(x) = \begin{cases}1& \mbox{-1 \le x< 0\par} \\ \frac{1}{2} \;\;\;& \mbox{x = 0\par} \\ 1 - x^2& \mbox{otherwise\par}\end{cases}{{/formula}}
===Case definitions===
{{formula fontSize="normal"}}f(n) = \begin{cases} n/2,& \mbox{if } n\mbox{ is even} \\ 3n+1,& \mbox{if } n\mbox{ is odd} \end{cases}{{/formula}}
[XWIKI CODE ENDS HERE]
Any suggestions?
The cases environment is not standard TeX, it belongs to the amsmath package. This means that it is not supposed to work using the default backend. It should work with the native one, which uses the amsmath package, and you could try using the mathtran one. If you decide to change the backend, you'll find instructions in the last paragraph on http://code.xwiki.org/xwiki/bin/view/Macros/FormulaMacro#HTechnicalinformati... -- Sergiu Dumitriu http://purl.org/net/sergiu/
