comment How to estimate the matrix condition number in the 2-Norm?
The former doesn't work for me in Mathematica 10. Did you need to import anything for it to work?

You can compute it yourself with Norm[mat,2]Norm[Inverse@mat,2], but this is unsatisfying...

Thanks for the answer. Why did you use pt and b and not pt_ and b_? I was under the impression that pt : ptrn would just specify a default value; is something else happening here?
