which subroutine calculate matrix norm?

[bsmile]

I am wondering whether there is a ready subroutine in calculating matrix norm in lapack. It is needed when I try to calculate condition number calling lapack dgecon. Many thanks!

Hi
DLANGE returns the value of the one norm, or the Frobenius norm, or
the infinity norm, or the element of largest absolute value of a
real matrix A.
