template<typename T>
TBCI::Matrix< T > invert ( TBCI::Matrix< T >  M  )  [inline]

returns the inverse of the input matrix

The plan is to choose the best/fastest method (lu_decomp sometimes does not work). Hopefully it is possible to implement the errorhandler to use gaussj a fallback method if lu_decomp falls over.
