Summary 

									
								

							

						

						
We describe methods to compute a veried inclusion of a basis of the
null space of a rectangular, real or complex matrix. The quality of the
inclusion correlates with the ratio of the largest and smallest singular
value of the input matrix. Some executable INTLAB routines are given.
