Hello,

the entry in the manual about the condition number reads:

"LinearAlgebra`MatrixConditionNumber[mat,Norm->p]  p-norm approximate 

condition number of a matrix, where p may be 1, 2, or \[Infinity]"

In version 6.0.2, if you try: Norm->2 you get the message that only 1 or 

Infinity is allowed.

As the 2 norm is the most common norm, it is hard to see why it should 

not work.
