template<typename _MatrixType>
bool FullPivLU< _MatrixType >::isSurjective (  ) const [inline]
true if the matrix of which *this is the LU decomposition represents a surjective linear map; false otherwise.
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&).
