Matlab LaTeX Interpreter: Minus sign in subscript or in superscript
Currently, I solved the problem by a small workaround but better / correct solutions are welcome. The workaround has been proposed by matheburg. Thanks for that!
Instead of $K_{-1}$
, I now use $K_{\!^{\_}1}$
. It sounds weird, but it looks similar to the minus sign. The underline is visible, so that I add an invisible negative space \!
and take the underline \_
as superscript.
