template<typename _MatrixType>
bool FullPivLU< _MatrixType >::isInvertible (  ) const [inline]
true if the matrix of which *this is the LU decomposition is invertible.
This method has to determine which pivots should be considered nonzero. For that, it uses the threshold value that you can control by calling setThreshold(const RealScalar&).
