Comment(by nschloe):

 Exact norm computation for sparse matrices may be difficult (just like
 condition numbers are hard to compute).
 There are however ways to estimate the norm; check out Higham's paper

 FORTRAN codes for estimating the one-norm of a real or complex matrix,
 with applications to condition estimation.
