* src/mathed/MathExtern.C (pipeThroughOctave): take into account that the output from octave may contain ansi control sequences. * src/mathed/InsetMathRoot.[Ch] (InsetMathRoot::mathematica): new virtual method to output n-th roots in mathematica syntax. * src/mathed/InsetMathRoot.C (InsetMathRoot::octave): octave has not a root() command. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@16559 a592a061-630c-0410-9148-cb99ea01b6c8
