Using matlab,I found that the condition number of matrix A(using the infinity norm,Koo(A)) (where A is is the Hilbert matrix with dimension n=200 ) is 3.8586e+020
Is this right or am I wrong?

No. It is probably a bigger number than that However, you forget the limits of floating point arithmetic.

As a followup, I decided to add a few linear algebra tools to HPF. So far this am, chol, LU, det were easy and now done. svd will take longer.

If you want to ask a separate question, then ask it as another question, not as an answer to your first question. When you ask it like this, you cause confusion, and make it difficult for others to follow.
